Calculation of energy required for grinding in a ball mill

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 ore 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
