Condition:New	Type:Ultrafine grinding mill	Capacity(t/h):0.5-12	Place of Origin:Shanghai China (Mainland)
Brand Name:Clirik	Model Number:HGM	Final Powder Size Range:325-2500mesh/47-5 micron

Application of the grinding mill

It is mainly applied to mill non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, etc., totally more than 100 kinds material

Features of the grinding mill

1.High Efficiency

Under the same finished final size and the same motor power, the capacity of micro powder grinding mill

is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.

2.Long lifecycle of spare parts

the lifecycle of spare parts is about one year, which is 2-3 times longer than impact mill or turbo mill.

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, flexible adjustment

The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.

Composition of the grinding mill

The whole set consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems

Working Principle of the grinding mill

The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. 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 blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, 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.
