LHG Roller Mill

Working Principle

After being fed into grinding chamber where the material is to be fine powders under the action of roll extrusion and shear and grind ,then transported to the separation sections by the airflow,and the coarse particle size and fine powders will be separated by centrifugal force of classifying wheel and fan.The unqualified powders will be rejected to the grinding chamber.The qualified powders will be collected by cyclone and bag filter.The purified gas will be discharged from the fan.

Features

LHG roller mill has been the first choice for ultrafine processing the nonmentallic mine of low oil absorption value in the plastic industry with the advantages of low consumption and particle size concentrative distribution etc.
1.Low energy consumption: innovative grinding structure design to save 30% energy compared with traditional roller mill,ball mill;
2.High fineness: Particle size D97≤3um is available with high precision classifying system;
3.Low wear: wear resistant material for grinding parts ensures longer service life;
4.High Capacity:large capacity can reach 7-8t/h when producing 1250 mesh calcium carbonate;
5. System control: intelligent feedback control,running smooth;
6. Environmentally friendly: operation under negative pressure and free of dust at the site.

Application

Our roller mills are primarily used for superfine grinding of various dry powder materials. This kind of grinding mill is extensively used in industries like nonmetal mining, chemical engineering, building material production, metallurgic, new material manufacturing, and food production, etc. 
Fibre texture material (Chinese medicine and wood powder, etc.) grinding are also possible.
