There are three ways for grinding media to pulverize materials: 1. Rolling: the grinding media rolls in the grinding chamber and pulverizes the material by selfweight. 2. Impact: with the rotation of the ball mill cylinder, grinding media falls from the high place in the grinding chamber and strikes the material. 3.

In this chamber the lining is typically a 'classifying lining' which sorts the media so that ball size reduces towards the discharge end of the mill. Here, comminution takes place in the rolling pointcontact zone between each charge ball. An example of a two chamber ball mill is illustrated in Fig. 15
