Ball Mill Throughput Capacity

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.
