Ball Mill
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.

Mills: What are they? How are Mills used? Advantages
Balls are used in ball mills to grind materials. The ball mill is switched on and allowed to begin rotating, either on its vertical or horizontal axis. The material is put into the chamber of the ball mill, where it is subjected to the spinning balls. The balls strike the contained substance as they bounce about in the ball mill while it spins.
