    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. Ball Size as Initial Charge. Commercial ball sizes 10150 mm Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed i.e. d↓V = 0.40 K√F
