DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

Porcelain lined hinged cover Standard design for all mills p in diameter and larger

Burrstone lined hinged cover Standard design for all mills 52 in diameter and smaller

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

Porcelain lined hinged cover Standard design for all mills p in diameter and larger

Burrstone lined hinged cover Standard design for all mills 52 in diameter and smaller

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

Burrstone lined hinged cover Standard design for all mills 52 in diameter and smaller

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

Burrstone lined hinged cover Standard design for all mills 52 in diameter and smaller

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

Burrstone lined hinged cover Standard design for all mills 52 in diameter and smaller

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

GEARS AND PINIONS

FINE PITCH MACHINE-CUT GEARS are standard equipment on PaulO Abbe Mills assurshying smooth quiet vibration free operation The strength safety factor is sufficient to carry loads many times the rated capacity of the Mills and for this reason with normal care they last for many years even on a twenty-four hour daily schedule The Ring Gears are bolted to steel pads on the Mill head and if replacements are ever necessary they call be quickly made on the job The outer circumference of the Gears is less than that of the Mill cylinder This provides maximum safety in operation and there is less chance of spilling material on the gear teeth

Note In some dry grinding operations it is deshysirable to completely enclose the cylinder with a dust housing In these cases gears can be installed on the outside of the bearing See Figures on pages 24 and 25

PINION LOCAnON

It is especially important to see that the countershyshaft or direct motor drive is securely mounted These are the first to feel the shock of the initial starting torque and must absorb a good portion of the running strains as well Centering the pinion at the bottom of the gear is the best insurance for smooth trouble-free performance and consequently all standard PaulO Abbe Mills are driven in this manner Some of the other advantages of this botshytom pinion mounting are listed as follows

1 Drive pressures on countershaft bearings and motor base deflected diagonally downward thereby distributing strains equally on base and bolts

2 Rotation of pinion can be made in either direction without affecting alignment or inshycreasing running strains This means effec tively doubling the life of both gear and pinion as well as increased convenience and versatility of installation

3 No extended bearing support-arm to allow swaying or misalignment

4 Pressure on bearings equalized

5 Correct alignment maintained insuring even meshing of gears

6 Mills run more quietly and smoothly than

with other types of mountings and power costs are less Gears wcar longer - many PaulO Abbe Mills have been running as long as 30 years with original gears despite continued service

7 Any drive installed does not protrude beyond the rim of Mill even when guards are included This minimizes floor space requirements

8 Less operating hazard because pinIOn is in stalled at bottom of large gear - out of the way

When desired other locations for the pinion are available

BEARINGS

Either babbitted or anti-friction roller bearings can be supplied with any PaulO Abbe Ball and Pebble Mill Our standard main bearings are bahshybitted with a high grade babbitt that has had the test of many years of successful service They are designed in accordance with the best engineering practice so that running friction is kept at a minishymum An extra large bearing surface eliminates the danger of bearing fatigue

A section of brick grease placed in the top half of the bearing provides sufficient lubrication for many months even when running on a twenty-four hour schedule

The countershafts of mills driven by V-belt or Silent Chain run at considerably faster speeds than the Mills hence self-aligning heavy duty anti-friction roller bearings are furnished on these countershafts

STANDS

PaulO Abbe Ball and Pebble Mills are mounted on sturdy stands providing adequate clearance under the discharging valve These stands are machineshyfinished on all metal contact surfaces and have extra wide feet for greater floor bearing and stability They are exceptionally strong and heavy and are designed to absorb all starting and running strains

There are many occasions when the height must be changed to meet special operating conditions If this is the case high or low steel stands can be provided Elevating the Mill can also be accomplishshyed with concrete sub-bases These are censiderably heavier than the steel stands however and should be avoided where the floor load is limited

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

DESIGN AND CONSTRUCTION

PATENTED STEEL FOR BALL MILL SHELL

The shell in a PaulO Abbe steel ball mill is

a patented Chrome Manganese Steel Every plate

is tested chemically and mechanically and must

meet wry rigid specifications before being passed for

construction A high tensile strength provides an

extra safety factor for the heaviest load of Balls

and Material The hard tough qualities of this

special patented steel reduce the danger of contamshy

ination excessive wear and ridging of the shell

Butt welded seams and joints made by skillful

welders provide a seamless smooth inner surface-shy

leak- proof and easy to clean We can furnish Liners

in place of the special Chrome Manganese Steel

Shell whenever desired in plain or corrugated types

and made of different kinds of metal to suit any

special operating requirements

BAFFLE BARS

(ebster defines a baffle as something which conshy

trols or directs flow No better description could

possibly be applied to the PaulO Abbe baffle bars

for they have been specifically designed to direct the

flow of balls and material in order to attain the most

efficient grinding action

A glance at the illustration shows why these

bars work so well The flat-sided baffle bars asshy

sure the maximum locking effect along the cylinder

wall All backward movement is thereby eliminated

The position of the balls does not change until

they reach the correct angle of break When they

finally break away from the cylinder wall they

achieve the swift maximum grinding energy which

occurs only when the correct angle of break is main

tained and backward slipping of the charge is eliminated

The bars are shallow eliminating excessive lift

ing or throwing of the balls The outer edges

in contact with the balls are smoothly rounded to

eliminate any danger of chipping or flaking There

are many advantages in this type of bar but the

most important are as follows

BAFFLE BARS

LOrKED

This row of Balls Iocked--no friction no wear on Shell while Mill revolves

1 Faster Grinding

2 More uniform results

3 No ridging of the shell thereby increasing its life by many years

4 Less wear to the ball charge

5 Less contamination because excessive wear IS

eliminated

PaulO Abbe baffle bars are made of a special

chip proof heat treated steel which resists the grind

ing and impact action of the steel balls They last

for many years generally as long as the shell itself

Since any projections inside the Ball Mill shell are

subject to wear there can be severe cases when the

baffle bars will not last as long as the mill shell

and must be replaced On such occasions replace

ments can be quickly and easily made on the job

since the bars are bolted to the cylinder

Welded bars can be- supplied where requested

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

DESIGN AND CONSTRUCTION

HINGED COVERS as illustrated are supplied complete flexibility in locating the loading side of on all Mills equipped with Built-In Discharge Valves the Mill This arrangement saves gaskets and insures constant Illustrations show standard designs with swing alignment of the cover The hinge is transferable bolts but crossbar closures can be furnished when from one side of the cover to the other permitting desired

Porcelain lined hinged cover Standard design for all mills p in diameter and larger

Burrstone lined hinged cover Standard design for all mills 52 in diameter and smaller

HANDY WEDGE BAR (above) breaks the cover seal quickly and easily by either a push or pull from above below or in front of the mill The bar is not attached to the Mill and after using may be placed to one side - out of the way

22

STEEL MANHOLE FRAMES are standard on all PaulO Abbe Mills They are welded to the Mill Shell thus eliminating any danger of leakage The flanges on the Pebble Mill Frames are detach able as shown above and may be easily replaced

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

ACCESSORIES

DOUBLE ROTARY UNION

()

H f ~

For chemical reactions drying distillation ctc

it is sometimes necessary to Jacket the outside of

the Cylinder for temperature control of the batch

and at the same time provide for drawing a vacutrm

applying pressure or introducing gases or liquids

to the inside of the mill The PaulO Abbe double

rotary union shown above has been designed to

permit the fluid for the jacket to flow to and from

the mill and at the same time leave the center of

the trunnion open so that the pressure can be conshy

trolled or the necessary fluids added to the batch

as the mill is revolving

AIR VENTS

All wet grinding mills are equipped with air vents

They are used for releasing pressure that might

build lip while grinding extracting samples at inshy

termittent stages of the grinding cycle and for atshy

taching an air line when air pressure is desired to

facilitate discharging These vents are generally

located in the head opposite the gear drive Bronze

plug closures are standard but other materials like

Steel Stainless or Cast Iron can also be supplied

GEAR GUARDS

Gear guards that totally enclose both the large

gear and pinion can be furnished when desired

They comply with all the safety regulations and also

prevent dust and grime from collecting on gears

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

WET DISCHARGES

WET DISCHARGE COVER

For discharging this cover replaces the grinding cover It is equipped with a grate which allows the material to flow out of the mill but retains the pebbles or balls It is possible to install a valve to control the flow if desired

COMBINAnON GRINDING AND WET DISCHARGE COVER

The Combination Cover like the Built-in Disshycharges elirninates the need for a separate wet dis charge cover While grinding a solid plug is retained in the opening of the cover and to discharge this is replaced by a grate plug which allows the material to flow from the mill and retains the grinding media

A valve can be installed on the outside of the grate plug to control the flow of material if desired

Combination covers are available with all types of mills and linings including steel ball mills Sup plied unhinged if preferred

PATENT DISCHARGE VALVE

This type of valve is usually installed opposite the manhole opening but can be supplied as part ~

of the grinding cover It eliminates the need for an extra discharge cover

-gtIt seals the mill inside the grinding chamber To

discharge a quarter turn of the handle lines up slotted openings in a sliding grate parallel with similar openings in a stationary grate The material then flows out through the openings and the grind ing media are retained in the mill

The grate surfaces are carefully ground to promiddot C _ Lngt vide a positive seal against leaks A coil spring applies constant pressure to seal the valve while the mill is running and control the flow of material during discharge

Not recommended with steel balls

BUILTIN DISCHARGE GRATE This type of valve is usually installed opposite

the manhole opening This valve has no internal closure While the slots remain open as the Mill is running the material does not pack in the space behind them because this area is constantly being flushed out as the cylinder revolves

A threaded opening is provided for a plug cock or some other type of quick acting valve if de sired

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs

GRINDING MEDIA

FLINT

PaulO Abbe imported French flint pebbles are the most popular and versatile of all grinding media Their irregular shapes exposing large grinding surshyfaces insure the highest degree of grinding efficiency and are particularly effective where very fine grindshying or complete dispersion is required in the shortest possible time These pebbles are extremely hard and dense thus eliminating all danger of contaminashytion and insuring perfect grinding results on the most delicate products

They are being used for grinding [rit glazes white and colored paints enamels and lacquers food products latex compounds aniline dyes graphite

Where a pure white grinding media is required a dense PaulO Abbe porcelain balls are recommended moisture Due to a carefully controlled manufacturing process cleaned they will not chip or break in service They have whether

For faster grinding PaulO Abbe high density porcelain balls are available in all sizes They weigh 4000 more than standard porcelain balls and this extra weight provides more efficient grinding es-

STEEL BALLS

PaulO Abbe steel balls are made of an alloy steel especially adapted for Ball Mill grinding and they insure the very highest quality finished product A uniform heat treatment provides a through hardshyness of 60 to 65 Rockwell C

They are supplied polished or unpolished The polished balls require no conditioning The unshypolished balls have all scale removed and will deshyvelop a high polish after a few runs
