A ball mill is another type of milling machine that uses balls to crush material. The ball mill is made up of a hollow section that spins down either a horizontal or a vertical axis. The section is packed with balls. The materials to be crushed are added and the balls move around inside the mill, colliding with the materials.

First, the weight loss of the ball leads to a decrease in its kinetic energy and a consequent reduction in energy transfer or milling efficiency. Second, the degree of filling of the mill is raised so the balls mobility becomes more difficult and as a result the kinetic energy of the balls are reduced.
