Ball mills produce 1 to 50 ton/h power of which near about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batch-operated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.

Up to 70% of the costs of materials size-reduction operations fall on the rock particle's size reduction from 30–50 mm to 20–50 microns . This operation is performed by the most common type of comminution equipment—ball mills. The design of ball mills was described back in the 18th century—and the principle of their operation has not ...
