Ore Grinding Mills-Types and Classifi ion - Mineral

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… Read More Ore Grinding Mills-Types and Classifi ion
