Grinding Mills: Ball Mill Rod Mill Design Parts

Ball mills are used extensively for grinding metal bearing ores and abrasive minerals. When grinding ore prior to concentration, on the other hand, the grind is determined by the degree of reduction necessary to unlock the valuable mineral from the gangue. This gangue is undesirable and must be separated from the desired material.

Mill Trunnion Liner - Mineral Processing Metallurgy

The Mill Trunnion Liner fits inside the bearing to protect it from wear caused by the ore being washed over the liner and through the bearing as it is fed to or discharged from the mill. The difference in the trunnions at each end of the mill isn’t in the trunnions themselves. The trunnion liner on the feed end of the mill may have a WORM to assist the ore into the mill. This worm acts like ...
