Bond Ball Mill Work Inde Hardness Jktech

Technical Information. The SMC Test is the most widely-used comminution test in the world for AG & SAG Mills, HPGRs and Crushers. The SMC Test was developed to provide a range of useful comminution parameters through highly controlled breakage of rock samples. Drill core, even quartered small diameter core is suitable

    Bond Work Index - an overview | ScienceDirect Topics

    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
