Ball Mills - an overview ScienceDirect Topics

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.

Autogenous and Semi-Autogenous Mills - ScienceDirect

2016-1-1  Pilot plant work by MacPherson and Turner showed that the ball charge should be about 5% of the mill volume. MacPherson and Turner thus recommend 3–8% of the mill volume needs to be steel balls. Reviewing the Australian scene, however, Siddall [1] observed that the ball load can be up to 15% for the grinding of lateritic ores under Australian ...
