The Bond ball mill grindability test measures hardness as an index, regardless of the feed size, so it does not give credit for the additional fines. Therefore, the index itself is ignored in the analysis and the results are assessed in terms of throughput rate or specific energy requirement.
Grinding wheel hardness. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond for steel would be in the 'F, G or H' range. A medium hardness would be in the 'I, J or K' range. And stronger bonds in the 'L, M, or O' range.
Bond's work index which is defined as the resistance of the material to grinding. The standard equation used by them for the ball mill work index (Bond work index) is as follows. / .

This guideline is for measuring comminution efficiency in global mine operations using the Bond method and comprehensive Bond Work Index. This method allows personnel to quantify and compare relative energy efficiencies and offers a mode of benchmarking to observe energy consumption.
grindability, Hardgrove grindability index, HGI, Bond Work Index, W. i. 1 INTRODUCTION . Grindability, as absolutely measurable physical quality of material has not been defined yet. Practical assessment of the resistance of the raw material against grinding is performed in laboratory facilities, in which
Bond Work Index FormulaEquation BASIC EQUATIONSSIZE DISTRIBUTION AND EXPOSURE RATIOEQUATIONS FOR WORK INDEX VARIATIONSWORK INDEX AND CRACK ENERGY The basic work index equation is:W = 10 Wi/√P – 10 Wi/√F(1)where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the work index, or the grinding .
Abstract: The standard Bond method is the most acceptable method for designing and selecting ball/rod mills described by their basic parameter called work index (W i). The standard Bond method is a tedious time consuming procedure requiring at least 7 – 10 grinding cycles, so that many researchers have tried to
