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. Plotting the database of …
