PAUL O ABBI ROTA-CONES-extensively used for all kinds of dry blending In a matter of minutes a thorough blend can be obtained regardless of the number of different materials and their comparative weights The mixing ~tion is extremely gentle and particle size and shape are not affected
The Rota-Cone is also extremely useful for uniformly adding limited quantities of liquid to a dry base An atomized spray rigidly positioned over the batch coats the constantly changing surface of dry material This ensures a uniform distribution of the liquid Wet areas in the batch and on the blender walls are avoided
The use of an agitating element greatly enlarges the usefulness of the Rota-Cone Blender Soft lumps are quickly dispersed and particle reaggregation is prevented Fibrous masses can be separated and blended with dry or liquid additives without seriously affecting their structure
The spraying and beating elements in combination or singly can also in many cases be used to advantage in the Rota-Cone Vacuum Dryers
PAUL O ABBE ROTA-CONE VACUUM DRYERS-efficiently and economically dry a wide variety of materials in the form of
Powders Chips Shavings Granules Pellets Filter Cake Flakes Crystals Slurries
Temperature sensitive materials can be dried at low temperatures because of the high vacuum obtainable Toxic fumes or vapors are always contained within the vacuum line and cannot escape into the working area Solvent recovering is possible by means of a condenser Particle size and shape are not affected even where friable flakes or crystals are involved Drying is rapid and thorough
PaulO Abbe Rota-Cones are of all-welded construction The completely asshysembled cones are lathe-turned to insure perfect alignment They are supported by rugged steel stands and the heavy steel motor base is an integral part of the main stand Heavy duty antifriction roller bearings are standard equipment Rota-Cone Vacuum Dryers are available in steel stainless steel aluminum Monel or bronze and they can be lined with rubber or plastic

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

(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

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

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

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
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

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

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

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
