  • Compare and Understand Rod/Ball/Impact-Crushing/Abrasion

    Relation of Bond rod mill work index and crushing work index. Similar to the ball mill work index the rod mill work index is a tumbling test that includes both attrition and abrasion breakage mechanisms. Unlike the ball mill work index the size of the feed to a rod mill test (10 mm–12 mm) is closer to the size of the crushing test.
