2020-5-18See this useful summary Table of Bond Work Index by Minerals. For any circuit whether a crushing circuit a rod mill or a closed ball mill circuit the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large sie to 100 um. The sample was received crushed appropriately for the ball mill test
