    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 11.5 times the shell diameter Figure 8.11. The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight.

    If a ball mill contained only coarse particles then 100 of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality the mill always contains fines these fines are present in the ball mill feed and are produced as the particles pass through the mill.
