tear on the mill The economic advantages of using a smaller bal1 load were discussed by Fahrenwald 4 Using a 12 inch ball mill it was shown that a 29 ball load was more efficient than a 49 load, since there was less overgrinding as well as an increase in material recovery and a reduction in power consumption...
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 indic...
