    Ore Grinding Mills-Types and Classification Mineral

    Jul 15, 2020 In the process of grinding, as in crushing, mineral particles are reduced in size by external forces, mechanical, thermal, hydraulic or electrical. Once the effect of such forces overcomes the internal forces of the solid structure, we have a comminution. Grinding, as a rule, follows crushing which generally ends at a size of 50 mm or less.get price
