What’s the working principle of grinding mill? Grinding plant consists of mainframe, speed reducer, powder separator, blower, bag filter, pipes, cyclone, motor, etc. The peripheral equipments are jaw crusher, bucket elevator, feeder, hopper, electric control panel, etc. Grinding mill can grind all kinds of non-flammable and non-explosive minerals with Moh’s hardness lower than 9 and humidity less than 6%，and is widely used in metallurgy, manufacture of building materials, chemical industry, mining industry, etc.

Large materials are crushed by PE Jaw crusher to the needed sizes firstly. Then the materials are elevated to storage hopper by bucket elevator. Thirdly, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separated by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products.
