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 ball mill is the important equipment in the mining industry, with the development of the macro-scale ball mill, and is more difficult of liner's wearing,installation and taking apart. The service life which raises a liner will prolong the production period that the ball mill, influencing an economic benefit of the concentrating mill.

The first limitation can be illustrated with a simple example: the most common tumbling mill used in the lab is the Bond ball mill, used to measure the widely used Bond ball mill work index . The mill dimensions, 30 cm in diameter and 30 cm in length, and the test conditions are standardized, with a maximum ball …
