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.

Mill Charge
Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

Confirming Dimensional Accuracy of a Precision Ball
One parameter is ball mean diameter (Dm), the arithmetic mean of the largest and smallest single diameters of a ball, which is calculated as Dm = (Ds max + Ds min)/2. To account for production variation between units, manufacturers typically measure in lots. Lot sizes typically consist of 10 balls, but in some cases can be 50 or more.
