Central discharge: The discharge port of the ball mill machine is located at the central shaft hole of the ball mill, and it can be divided into two types. Overflow type central discharge ball mill: when the ball mill machine is grinding, the material surface in the mill must be higher than the discharge port, so that the material overflows.

Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semiautogenous grinding (SAG) mill followed by a ball mill (two stage circuit).

Peripheral Discharge Ball Mills. The several layers of balls lying on top of those next to the shell follow a similar cycle except that, due to relative difference in the two forces, their paths become more nearly vertical. The outer layers, spreading more than the inner layers, increase the area in the zone of the falling balls.
