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.

For the stirred media mill with a disc rotor the stress energy where the peak value occurs is higher – compared to the cylindrical rotor – but the peak ratio is reduced. Additionally, with increasing grinding media size the ratio decreases. The planetary ball mill offers a wide range where rolling is the dominant component.
