### Ball Millsan 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.
