Grinding kinetics of quartz and chlorite in wet ball milling
Laboratory batch wet ball milling tests of quartz and chlorite were carried out for four feed size fractions (− 2 + 1.19 mm, − 1.19 + 0.5 mm, − 0.5 + 0.25 mm,-0.25 + 0.15 mm). The results showed that both quartz and chlorite demonstrated the first-order breakage behavior in the feed size range investigated.

Ball Mill
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.
