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.

Milling is among the most energy-consuming technological stages of copper ore processing. It is performed in mills, which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive systems.

2.2.3 Interpretation of laboratory tests (concept). The concept of measuring W i is the following. We put a total mass M T of ore to be milled in a small laboratory grinder. After a determined number of rotations N T, we empty the grinder and sort the mass M T on a sieve with an opening P 1.The mass of the underflow is M P = M T − M R, where M R is the mass of overflow.
