Certain ball size will have proper trajectory (given mill rot speed and liners). It's for everybody's sake (high production and low costs) important that the maximum ball size strike location on the mill to be at the correct toe/shoulder trajectory estimations, but still on toe, therefore over the ball charge, not on liners (easy if we think a

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
