An identical weight of the test ore is then ground for a length of time such that the power consumed is identical with that of the reference ore. Equation 1 gives the work index of the ...
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.
