The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet. The proportion of the mill-exit material returned to the inlet may vary from 10-30% when ordinary

of the energy generated by the mill is utilized for actual grinding of the ore [2]. This inefficiency is a result of various factors such mill load, rotation speed, type of milling (wet or dry) as well as the size of the steel balls [3]. Mills are also one of the largest energy consumers in processing plants which can be estimated to about 50% of the total energy utilized in minerals
