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.

2, more crushing and less grinding, reduce the granularity of grinding. If the grinding particle size is large, the more work the mill needs to do to the ore, the more the workload of the ball mill is bound to increase, and the energy consumption and power consumption will also be increased in order to reach the prescribed grinding fineness.

The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).

When the specification and rotating speed of the ball mill are fixed, the filling rate of the ball mill is in the range of less than 50%, and its production capacity will increase with the increase of the filling rate. Therefore, the first loading ratio of ball mill should be calculated according to this formula.
