High Capacity Pendulum Roller Grinding Mill Precise Powder Fineness Control

Product Specification

80-400 Mesh Pendulum Roller Grinding Mill with Bigger Roller and Ring:

How to start pendulum roller grinding mill:

Start pendulum roller grinding mill according to following procedures:

(1) Start elevator.

(2) Start crusher. Materials can be lifted to be crush after the complete start so that there are enough raw materials in hopper.

(3) Start classifier and set the rotation speed in accordance to the required fineness.

(4) Start blower, and open the valve of air-in pipe after complete start.

(5) Start the main unit. In order to avoid excessive abrasion of grinding roller and ring and vibration of the mill, and idle running time of the main unit should not last too long and should be less than two minutes. In order not to overload the main unit, it is not allowed to put too much raw material in it when start.

(6) Start the magnetic vibration feeder, and set the amplitude as required.

(8) Start the discharging valve.

How to stop pendulum roller grinding mill:

① Stop the crusher, and then stop the crusher until there are no raw materials in the crusher.

② Stop the elevator until there are no raw materials in it.

③ Stop the feeder.

④ Do not stop main grinding mill immediately. Stop it in one minute after the grinding is finished . Make sure there is no material left when stop the mill, which will shorten the next start time and extend its service life.The fan should be turned off in 30 seconds after the mill stops. And put the air-in pipe valve to the STOP.

⑤ Stop the pulse classifier.

⑥ Stop the discharge valve

Working Principle of Pendulum Roller Grinding Mill:

   The crushed raw materail with a size of less than 20mm will be conveyed to the hopper by elevator. And then the raw material will go into the grinding house with the help of belt conceyor at a fixed rate. The rollers hung upon the spider-arm are running around the shaft. With the help of the centrifugal force, the four or five rotational rollers will go around the ring tightly. The raw material is lifted up between the rollers and rings by the blade, and then to be ground into powder.

   The powder is blown up to the classifier, through which the powder is classified. Coarse particles fall back down to the mill for regrinding. The needed particles will go into the collector,where products will be collected through the discharge opening. The purified air goes into the fan through the pipe above the cyclone collector. Air stream in all pipelines is negative pressure except for that in the fan and grinding chamber. Air volume in the whole system increases because of the gas from the moisture in the raw material and the air from the flange conjunctions and feeding-in opening. The extra air volume goes into the pulse jet powder collector. The ultrafine powder in the air stream can be collected through the discharging valve.

Improved Performance of Calcium Carbonate Pendulum Roller Grinding Mill

1. The grinding mill is in stereo-chemical structure, consume small floor space.the equipment has strong systematic because it can organize an independent and complete production system of raw material crushing, transporting, grinding to production collecting, storing and packing.

2. Applied high quality thicken steel to produce important parts, applied high performance wear-resistant material to produce wear-resistant parts. The equipment has high wear-resisting property and reliable operation.

3. The electric system is applied with centralized control, which will offer unmanned workshop operating and convenient maintenance.

4. Pulse dust collector can be equipped according to customer requirement, dust collecting efficiency can reach 99.9%, which is high efficiency and environmentally friendly.

5. Maintenance-free roller assembly and new spider-arm structure ensures the reliable performance and easy maintenance.

6. High capacity: system upgrading and reasonable solution guarantee higher production capacity.

7. Highly-precise classifying: the turbine classifier can achieve a fineness ranging from 80 mesh to 400 mesh.

8. Large air conveying capacity: centrifugal fan with high pressure and air volumn is used to improve the air conveying capacity.

9. Larger lifting capacity: newly-designed and super large lifter can convey more raw materials between ring and roller.
