  • Bond Work Indexan overview ScienceDirect Topics

    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 being ground and hence have an impact on the energy used in the mill for grinding.
