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.

Dynamic sampling. Superior methods of powder sampling are obtained by using procedures where the sample is removed from a moving powder bulk. Again, there are three basic methods: (i) table sampling, (ii) chute splitting, and (iii) spin riffling. Table sampling involves powder flow along an inclined table in which there are a series of holes.
