SAG Mill Testing Test Procedures to Characterize Ore

rod mill grindability tests. As discussed earlier in this paper, it is important in this case to match the reduction size of the test to that desired from the industrial mill. As such, primary ball mills should be designed with the rod mill work index, and single stage ball mills should be with both the rod mill and ball mill indices.
