  • Bond Impact Crushing Work Index -Procedure and Table of

    Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is

  • QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE

    grinding cycles. The Bond Work Index is calculated using the formula: Andesite and limestone samples were prepared by crushing in a laboratory jaw crusher and roll crusher in a closed cycle with screening to size 100% -3.327 mm. Composite samples of andesite and limestone were prepared in ratios: limestone : andesite = 25 : 75, limestone : andesite = 50 : 50, limestone : andesite = 75 : 25

  • Bond Work Index an overview ScienceDirect Topics

    The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and

  • CORRELATION BETWEEN BOND WORK INDEX AND MECHANICAL

    The Bond's 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 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work

  • Comminution Wikipedia

    Bond's law, which assumes that (primary crushers) are the jaw crusher (1m > P 80 > 100 mm), cone crusher (P 80 > 20 mm) and hammer crusher. Primary crusher product in intermediate feed particle size ranges (100mm > P80 > 20mm) can be ground in autogenous (AG) or semi-autogenous (SAG) mills depending on feed properties and application requirements. For comminution of finer particle size
