Therefore, it is critical to ensure that mills are operated in an optimised mode. As shown in Fig. 1, an optimised mill entails that mill parameters including steel balls, rock and water loadings, the mill speed, and the liner mechanical design, result in grinding mechanism as well as the liner wear life satisfying the economic production requirement [24].

According to Swart et al. [9], ball mills are mostly used because of their very high size reduction ratio, although they have a very low energy efficiency of about 20%. According to Conger et al. [10], many factors affecting ball mill efficiency include mill design, liner design, mill speed, charge ratio, and grinding media properties.

Modern ball mills consist of two chambers separated by a diaphragm. In the first chamber the steelalloy balls (also described as charge balls or media) are about 90 mm diameter. The mill liners are designed to lift the media as the mill rotates, so the comminution process in the first chamber is dominated by crushing.
