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 effi-ciency include mill design, liner design, mill speed, charge ratio, and grinding media properties.
