Optimization of mill performance by using SciELO. This test also shows that by feeding the mill with a too dilute pulp the grinding zones between the media are not saturated leading to high media wear rate A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion This could help the operator to make the right decision and keep the 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.
