The Effect of Ball Size Diameter on Milling Performance | OMICS .

Approximately only about 20% 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.
