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.
the bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the bond work index . the test is a 'lockedcycle' test where ground product is removed from test cycles and replaced by fresh feed. the test much achieve a steadystate before completion.
