The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill see Figure 3.10, a question arises as to whether this practice will alter the ball mill work index BW i of the material ...

3- STANDARD BOND TESTS The Bonds standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80 passing 100 m. If the breakage
the bond ball mill work indices determinations gave reasonably reproducible results, significant variation was observed in the measurement of the bond rod mill work index on at least one sample tested, and large variations in abrasion index and crushing work index were due to variations in the test method across the laboratories.
typically used. The rod mill work index is computed with an equation very similar to that of the ball mill test, as follows It is common to observe a difference between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore hardness by size 12.5mm for RWI and 3.35mm for BWI, andor grain ...
