Ball Mill Grinding  William Boulton
Ball Mill grinders are designed to reduce materials down to a fine powder, using the impact and friction created by a large quantity of balls – generally made from steel, but also available in other materials for specific applications – which are placed inside a rotating mill to create a cascading effect.

Ball Mill  an overview ScienceDirect Topics
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.
