More specifically, in the case of an overflow mill, at constant ball filling, the mill performance increases as the pulp volume becomes more compact (mainly at the shoulder) and as the ball load expands (mainly at the toe). – At constant ball filling degree, this mill's performance increases as the pool angle and dry ball angle go toward zero.

Milling (grinding) charges and the mill feed material (pulp) are placed in the steel drum. The grinding charges are usually round in shape (balls), but may include other forms such as cylinders and prisms. The ratio of the grinding charges to the volume of the drum determines the filling factor of a ball mill.
