    Very large tonnages can be ground with these ball mills because they are very effective material handling devices Ball mills are rated by power rather than capacity Today, the largest ball mill in operation is 853 m diameter and 1341 m long with a corresponding motor power of 22 MW (Toromocho, private communications)The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many lowgrade, hightonnage operations such as copper and gold ores feasible Future circuits may see increasing use of high pressure grinding rolls (Rosas et al, 2012)Grinding Circuit an overview | ScienceDirect Topics
