### Bond Tests Mining SGS

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond s Third Theory of Comminution to calculate net power requirements when sizing ball mills . Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill. As the size reduction ratio increases the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128 1 (Fig. 7d) a 50.8 mm/25.4 mm ball mix at a 13 87 ratio was found to be the optimum mix. This indicates that the finer the product size the higher the proportion of smaller balls that is required.
