C This value represents the Volumetric Fractional Filling of the Voids in between the balls by the retained slurry in the mill charge. As defined, this value should never exceed 100, but in some cases 8211 particularly in Grate Discharge Mills 8211 it could be lower than 100. Note that this interstitial slurry does not include the overfilling slurry derived from the difference between the Charge and Ball Filling.

In this equation, E is the specific energy required for the grind, and F80 and P80 are the sizes in micrometers that 80 of the weight passes of the mill feed and product respectively. The parameter Wi, known as the work index of the ore, is obtained from batch bench tests first devised by Bond 1961. The power calculated on using equation 1, Bond, 1961 Rowland and Kjos, 1978, relates to.
