Size Reduction and Energy RequirementScienceDirect
A Bond ball mill work index is then performed on the mill product for the design of SAG ball mill circuits This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing.
