The length and diameter of a SAG mill are determined principally by the desired throughput capacity and the grindability of the ore. For conventional ball mill grinding, grindability is usually expressed in terms of the Bond Work Index, which is determined in laboratory tests and expresses numerically the power required to reduce rock from a

The aim of this paper is to assess the effect of microwave treatment on copper sulfide ore for ball milling and bed breakage. Liberation analysis of ground products in eight size fractions showed that microwave pretreatment liberated more chalcopyrite particles from the bed breakage product than the ball mill product. In bed breakage, microwave pretreatment caused a 2 increase in chalcopyrite
The 1500t/d Pakistan copper mine project uses a continuous copper ball mill for copper mining as the main equipment. The rawposition of the project is relatively simple, and the metal minerals are mainly chalcopyrite and pyrite. Theponents of nonmetallic minerals are quartz, chlorite, etc.
