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.

A mill load is defined as the instantaneous total charge of a ball mill and is composed of a new feed ore, slurry, water, and steel balls inside the mill (Tang et al., 2015a). Overloading causes “mill spitting ore,” coarsening on the particle size of mill outlet, “mill blockage,” “belly be filled full,” and production process break off.

Based upon a simplified grinding mechanism, an analysis of the selection function is made for vibration mills. The mechanism considered is that a particle nipped by two colliding balls is to be ground only if the ball impact generates or activates at least one crack within the particle and the crack is big enough for fragmentation.
