　　Working principle of course grinding mill

　　European Coarse Grinding Mill is mainly made up of main case, rotor, impact plate and grate. The main case consists of fluctuation two parts and is welded by cutting steel plates, and the others are connected with bolts. There are high manganese steel liners embedded in the main case, which is convenient to be replaced after wearing. Several uniform weighted blow bars are installed on its spindle and are all tightened by highly strengthen bolts. The main engine drives spindle through motor and v-belt, makes the rotor do movement to and fro, large rocks go into the crushing cavity from feeding opening and then be crushed by high speed moving blow bar. Crushed qualified materials are discharged from the interval between grates at the bottom, while the unqualified are still kept in the crushing cavity, crushed by rotor and blow bar repeatedly till they meet the established requirements. To avoid jams, the water content of materials to be crushed is not more than 20% generally.
