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 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of theBond work index value of these components mixtures is greater than the Bond work index of harder components, clinker Oner (2000) have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass proportions He found out that these values are always lower than the Bond Index obtainedTHE BOND WORK INDEX OF LIMESTONE AND ANDESITEAug 01, 2008· The Bond ball mill test provides the socalled standard work index (WI), defined as the specific power required (kWh/t) to reduce a material from a nominal infinite size to a P80 (80% of the material passing through a sieve aperture) size of 100 μm , The influence of mineralogical, chemical and physical

the Bond ball mill These variations are critical in computer simulation of any test aiming to minimize the experimental efforts of the standard procedure As a result of the back calculation of breakage rate parameters for clinker and trass samples in the Bond mill, no common pattern was seen for the variation of the rate parametersStandard Bond tests showed a reduction in the Bond ball mill work index (wi) of the mineral sample used in this study when using Relo grinding media The modified Bond test procedure is based on using the standard Bond ball work index test but changing the circulating loads (350%, 250%, 150%, 100%)A Comparative Study of Energy Efficiency in Tumbling
