White stone is the main mineral composition of dolomite and dolomitic limestone of. White stone can be used in building materials, ceramics, glass and refractory materials, chemical industry and agriculture, environmental protection, energy saving, etc. Mainly used as alkaline refractory and blast furnace ironmaking flux; Preparing calcium-magnesia phosphate fertilizer production and magnesium sulfate; As well as the production of glass and ceramics ingredients.
White stone is dolomite, series products of all kinds of quality dolomite: dolomite ore, dolomite sand 6-10, 10-20, 20 to 40, 40-80 mesh, 80-120 mesh, 10 mesh by dolomite fines, ultrafine dolomite powder, 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh. Clirik white stone grinding mill can processing dolomite to all the mesh of the above.
There are five types of Shanghai CLIRIK White stone grinding mill, they are HGM80, HGM90, HGM100, HGM100A and HGM125. The finished production fineness can be reached 300meshes~3000meshes, 5-47 micron. The capacity (ton/hour) ranges from 0.4T/H to 12T/H.
Working Principle of White stone 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.

Features and advantages of white stone 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.
5、Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
