The popular grinding mills for calcite are Raymond mill, ultrafine powder grinding mill , coarse powder mill. Calcite powder is available from 100 Mesh to 2500 Mesh. Production Line Configuration of HGM series Calcite powder grinding mill: The whole set Calcite powder grinding mill consists of 1). Hammer crusher, The popular grinding mills for calcite are Raymond mill, ultrafine powder grinding mill, coarse powder mill. Calcite powder is available from 100 Mesh to 2500 Mesh.
Production Line Configuration of HGM series Calcite powder grinding mill:
The whole set Calcite powder grinding mill consists of
1). Hammer crusher, bucket elevator, storage hopper, vibrating feeder,
2). Main unit, inverter classifier, cyclone collector, pulse deduster system,
3). High pressure positive blower, air compressors and electrical control systems.
Working Principle of Calcite powder grinding mill:
●The crusher will crush the big materials into small ones, and then the elevator will send them to the hopper.
●The vibrating feeder will send the materials to the middle of first dial evenly.
●The motor of main equipment drives the main shaft and dial through reducer, and the dial drives numbers of rollers moving in the ring channels via pins.
●The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings.
●The high pressure centrifugal blower will inhale air from outside and bring the crushed materials to classifier.
●The rotating turbo in the powder collector will make the coarse materials return to the mill and regrounded, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it.
●The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
Advantages of Calcite powder grinding mill:
- l、 High efficiency
Under the same finished final size and the same motor power, the capacity of grinding mill is twice as much as jet mill, mixing grinder and ball mill.
- 2、Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
- 3、High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
- 4、 High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
There are five types of Shanghai SBM Calcite powder grinding mill,The finished production fineness can be reached 300meshes~3000meshes, 5-47 micron. The capacity (ton/hour) ranges from 0.4T/H to 12T/H. SBM ore mineral crushing, screening, grinding mill has been exported to many countries which includes China, India, Pakistan, Malaysia, Vietnam, Thailand, Egypt, Nigeria, South Africa, Brazil, Canada, Columbia, Chile, Australia, Russia and so on.
