vertical mill grinding of coal dust

Vertical Coal Mill - Great Wall

Great wall Machinery Vertical Coal Mill with advanced grinding mode, so that energy consumption is reduced by 30%~40% compared with that of ball mill. Due to its unique sealing structure design, the whole system is under negative pressure, so there is no dust in the production process, noise.


Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal.
