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.

Where, y is cumulative percent passing size d, d 50 is the 50% passing size, n is distribution constant, and k is a correction factor. The n values ranged from 0.84 to 1.84, and k values from 0.95 to 1.00. By using the Bond method of grindability, H. Ipek et al. [4] have observed that less specific energy input is required in separate grinding of ceramic raw materials than grinding them in
