An Alternative Energysize Relationship To That Proposed
Nov 19, 2004 The Bond laboratory ball mill work indices were available for all of the 27 data sets and were initially used in Bond's equation to predict what the specific energy should be in the full scale AG/SAG and ball mill circuits. The feed and product sizes measured from each circuit were used. No correction factors were applied.
