    Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack EnergyThe basic work index equation is:W = 10 Wi/√P – 10 Wi/√F(1)where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the work index, or the grinding resistance parameter. It represents the energy input required in kilowatt hours to reduce a short ton from theoret在911metallurgist上查看更多信息
  • Bond Work Index (Energy equation) - Grinding ...

    2020-6-13  BOND WORK INDEX. The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore. The Bond's Work Index equation is: W=WI* (10/√P80 -10/√F80) where. W= the energy input (Work input) per ton, kwh/metric ton. WI= Work Index= specific energy per ton, kwh/metric ton (characterizes the ore)

  • 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 ...
