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.
In addition to wear speed, ball size and recharge practice, charge volume, and feed rate are significant factors affecting the actual production wear rate. Wear speeds are largely independent of ball size and ball charge volume. The wear rate exponent for SAG milling was experimentally determined to …
