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.

The speed of ball mill directly affects the motion state of steel balls and ores in the ball mill. When the speed is too slow, the steel balls and ore will slide down without rising high, and the crushing effect will be small; when the speed is too fast, the grinding medium will attach to the inner wall of the ball mill and rotate.
