Bond Work Index Formula-Equation 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

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.

The bond work index of granite is expected to be the highest due to the ore being mostly composed of the hard mineral quartz. Bond Work index values of granite presented in literature range from around 14-15. Limestone is theorized to have a Bond Work index with a value of around 11. This is due to the main presence of calcite, a softer mineral.
