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 self-weight. 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.Web

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.Web
