1.1Explanation of Symbols1.1.1 Personal danger

Warning notes indicated this symbol, which if not strictly observed,

could result in personal injury or possible death.

1.1.2. Possible damage to equipment

Caution notes indicated this symbol, which if not strictly

observed, could result in property damage or destruction of the

equipment.

1.1.3 Technical characteristics

This symbol is used for the attention to special technical characteristics.

1.2 Prohibition work

Do not step on the rotary feeder.

Do not disassembly in operation.

NOTE

Do not insert hands, tools or other foreign

object into openings.Failure to observe this warning may result in

bodily harm or death.

Keep chain cover in place

Do not start until all guards and covers aremounted in their proper place.

Failure to observe this warning may result in

bodily harm or death.

Any maintenance and disassembly should be done as follows

1Reduce internal pressure to be same as atmospheric pressure.

2stop to supply the gas while cleaning.

3Shut off the power. Functions of Each Parts

Drain Plug

For easily melting powder and pellets, gas-cleaning must be done.

Overload formed after accumulate powder melted, rotary feeder stopped to

rotate.

For Type BP, gas-cleaning from here.

Clean of Shaft

For type BVSBPSBVSTBPST, to prevent power

stop between the rotor and side board, remove the

drain plug to apply and clean the gas.

Remove the upper drain plug to apply, gas pressure

10~20kPa higher than system pressure.

Remove the under drain plug to clean, gas pressure

10~20kPa higher than system pressure.

For type BV/ BP/BVT/ BPT, to prevent gas leaks

caused by the powder inside the feeder, remove the

drain plug to apply or clean, gas pressure 10~20kPa

higher than system pressure.

Be sure to clean the shaft, otherwise may cause gas leakage an also increase the abrasion of

packing gland.

Options

Dead Block

Vent Chamber

Vent Pipe

While transporting hardy pellets, install the dead block

upside the rotary feeder to relax the impact, or reduce

the fragmentation of pellets

While the out pressure is obviously higher than inlet,

gas leakage will prevent falling of powder and pellets.

Vent chamber installed for the purpose to deal with

this gas leakage.

Vent pipe can deal with gas leakage if no space for

installing vent chamber while materials are pellets.

Do not disassembly vent-pipe to avoid cutting off the fingers.

Gas leakage may include powder, so vent pipe can not have the sameeffect as vent chamber.

INSTALLATION

Portage

Serious accident may happen while falling.

Lift job should be done by the persons who learn the lift technical or take the

safety education of lift job.

Method Using four steel ropes to lift.

Following values are for safety load:Model: GR7-600 GR800-1600

Safety load: 1,000kgs 2,000kgs

Note: For the quality of rotary feeder, reference the drawings when delivery.

Installation

Repairing place needed when installing the rotary feeder.

Remove the safety film in the flange before install the

associated piping.

Unload operation

To confirm load of the associated piping, and no foreign materials in the casing, do

follow the instructions:


7/14

7

Serious accident may happen while operating.

Follow the safety instructions:

Check the load of piping connected and no foreign materials in the casing.

1Shut off the power after installing the associated piping.

2Remove chain cover and chain.

3Rotate the feeder manually. Make sure that it rotates smoothly.

Loosen packing gland and make rotary feeder rotates smoothly if feeling itrotates tightly.

Unload operation

1Check all the associated piping connected.

2Feed the geared motor with an adequate and proper volume of lubricating oil.

Motors with a grease lubrication system are already provided with grease.

3Confirm the chain cover well installed.

4Check the rotational direction.

5When above check is completed, operate the feeder 15~30 minutes with no load,

and make sure that no abnormal sound is generated.

6Tighten the gland packing again if gas leaks between the packing and the shaft.

7If no vibration and noise, unload operation finished.

Periodical Maintenance

It is important to do the maintenance periodically to make sure the well-running of the

rotary feeder, or faults happened before the date of maintenance.

1Periodical inspection monthly.

2Periodical inspection annually.

Periodical inspection monthly

Check the Noise or vibration.

Check the Leakage of packing gland.

Check tense of Chain.Add oil to the chain.

NOTE

Periodical inspection annually.

Disassembly the rotary feeder.

Check and clean all the parts.

Replace gland packing.

Replace bearing ( if damaged)

Replace damaged parts.

Replace O-ring and oil seal.

Adjust the clearance.

Add lubrication oil.

Note: Maintenance of the geared motors must follow the manual instructions of

manufacturer.

Instructions for disassembly and assembly

For all work, observe the safety instructions in section 1.

Disassembly

1Remove the chain cover, chain and sprocket.

2Remove the pipes connected to the rotary feeder.

3Before disassembling, measure the clearance between the casing and the rotor.

Record all the measurement values of the clearance.

4Loosen the gland.

5Remove the taper pin.

6Remove the bolt and then the bearing covers.

7Remove the lock nut and the lock washer.

The teeth of the lock washer are folded up to engage in the lock nut recesses.

Before unfolding the washer teeth, mark on the nut and washer to indicate which

tooth corresponds to which recess.

NoteTo adjust the clearance, sometimes add a spacing ring between the block and

roller bearings. Check no parts are missing before assembly.

10Remove the side board.

11Remove the rotor from the casing slowly and squarely.

12Remove the gland packing and the lantern ring if present. Remove oil seals, roller

bearing, ball bearing.

ASSEMBLYType BVSBPSBVSTBPST

1Check that no parts are missing, and that each part is free from damage.

Damaged parts should be replaced.

2Clean the disassembled parts.

Especially clean the sections directly exposed to particles and inside the casing

cylinder.Clean and regress the bearings.

3Fit the gland packing, lantern ring(if present), and the gland.

Do not fasten the nuts tightly.

4To replace the bearings, tap the roller bearing into the rear side cover housing, the

roller bearing outer ring into the front side cover housing, and the inner ring onto

the shaft using, for example, a flat chisel.

5Insert the rotor into the casing. Do not twist when inserting.

6Type BVBPInstall side board(driven side) to the casing, fasten the screw tightly.

Type BVTBPTOrderly install side board and bearing base(driven side) to the

casing, fasten the screw tightly

7Drive the taper pin, fasten the bolt tightly.

8Install the ball bearing. To avoid the damage of ball bearing,

be sure to follow right drawing, install

inner and outer ring simultaneously, and

symmetrically use the force into the place

where lock nut can go, then, fit the lock nut, install the roller bearing to setting

place.

8Install the lock washer, fasten the lock nut so that the marks on the washer and the

nut coincide, and fold the lock washer teeth into the nut recesses again.

tightly.

Type BVTBPTOrderly install side board and bearing base(drive side) to the


11Drive the taper pin tightly, fasten the screw.

14Measure the clearance between the casing and the rotor and compare the value to

the one obtained before the disassembly.

Repeat the reassemble if the values are lower than the values measured before thedisassembly or the lowest allowable value the Inspection Report indicates.

15Orderly install the spacing block, end thrust ball bearing and locking collar.

Make sure to install the spacing collar (if have) between spacing

block and ball bearing , otherwise the value of clearance will be high and cause

damage of rotary feeder.

TROUBLESHOOTING

Trouble Source Action

Noise

Flour between casing and rotor Gas washing from the part of drain plug

Touch of casing and rotor Enlarge the clearance to be proper


12/14

12

Flour adhere inside the casingflour smelt

and the clearance of casing and rotor

disappears

Lessen the dimension of rotor surface

Vibration

Chain tightness Loosen the chain properly

Particle in Install buffer plate

Lack of

displacement

Particle is blocked during falling due to the

effect of air leakage

Take measures to air bleeding

Volume weigh of particles is not same as

design value

Increase the speed to be proper

Chucking

Casing deformation

Temperature rises and over the clearance

temperature.

Install soft pipe on or below the rotary

feeder

Enlarge the clearance to be proper

NotesTouch of casing and rotor may cause damage of rotary feederrotating drag

increasing, most time can cause motors trip.
