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.
