OEM China 21 Roller Mill - LHI Vertical Impact Mill – Zhengyuan

LHI Vertical Impact Mill Working Principle Raw material are fed into grinding chamber through feeding device,and crushed by high speed rotary hammers.Coarse and fine powders will be separated by classifier,coarse powder will rejected into grinding chamber for crush again,fine powder will be collected by cyclone and bag filter.


1. Both the grinding rotor and classifying wheel are driven by the same motor, which has the advantages of compact structure, high energy-conversion efficiency and low energy consumption. 2. The grinding rotor, rotating speed of classifying wheel and the wind volume can be adjustable. The LHI vertical impact mill can produce the med-fineness finished products within D97=25~150μm and is also more suitable for producing the finished products whose particles are narrowly distributed. 3. The crushing parts featured with long service life use the new composite wear-resistant materials. Processing the materials whose Mons' hardness scale is less than 5 is pollution-free. 4. LHI vertical impact mill is featured with quick-opening structure. And the complete machine is easy for dismounting and cleaning, and suitable for refueling operation. 5. LHI vertical impact mill has the advantages of compact design, less space demand and cost-effective. 6. It is featured with overall pressure-resisting design. LHI vertical impact mill uses the inert gas closed-circuit circulation device for smashing the inflammable and explosive materials.
