- Regrind Ball Mill Sizing Calculations

Jun 01 2009 The reason regrind ball mill operation has a higher indirect energy than the IsaMill operation is that it carries a penalty for using steel as grinding media. Overall there was almost a 15 decrease in the direct energy consumption when the IsaMill was substituted for the regrind ball mill.
