Mill Sizing: After laboratory and pilot plant testing confirm the feasibility of autogenous or semi-autogenous grinding, it can be used to establish the exact grinding circuit and mill size.In the pilot plant tests, the tare power of the pilot plant mills should be determined before and after each test run. The tare power should be for the empty mill.
