Firstly, raw crusher is crushed by jaw crusher to the size satisfied, and then elevated into a hopper, from where the material is transported by the electro-magnetic vibrating feeder, evenly and continuously into the grinding chamber for grinding. Materials are sent to the space between roller and ring by shovel for grinding. The milled powder is sent to separator by air.
Fine powders satisfied enters cyclone collector and discharged as final products. The air goes back to blower from upper part of cyclone collector. Coarse powders will be sent back for regrinding. The system is sealed and cycled under positive and negative pressure.
