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 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.

Too small a grinding ball (what size is your?) Sometimes, you solve scatting by charging the ball mill correctly (I saw cases where the mill was up to 15% under power). Other times, you need to enlarge the ball size diameter ie: using a 75 mm ball instead is 35 mm. Other times, you must control and reduce the feed size (crushing circuit product).
