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.

Grinding kinetics of quartz and chlorite in wet ball milling
Fig. 2, Fig. 3 plotted ln(m 1 (t)/m 1 (0)) as a function of grinding time t for quartz and chlorite at various feed size fractions during wet ball grinding, respectively. As can be seen, ln(m 1 (t)/m 1 (0)) showed a good linear correlation with grinding time t in the range of feed sizes investigated. The results indicated that both quartz and ...
