The analysis of the feed size fort the two samples was found graphically to be 180m and 175m, and ball mill discharge was 130m and 140m respectively. The work index of a coal as reference material was kWh/ short ton, this was used to calculate the work index of the graphite which was found to be kWh/short ton, being the required energy to comminute one ton of graphite.

The test determines the Bond Rod Mill Work Index which is used with Bonds Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied.
The Bond work index, W i, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of grinding product, the value of the work index W i
