This is because work index frequently changes as a function of the product size in comminution If target grind size during a project is changed or if the test is run at the wrong product size then it is necessarily to provide a correction The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis

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
