Ball Mills 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.

b) Ball coating which influences grinding efficiencies and in the worst cases grinding rates. c) Mill sweep dust collector efficiencies (Bag coating for baghouses or gas conditioning for ESP's). Depending on the mill circuit, different locations can be used for effective water sprays, but in all cases some atomization is required as well
