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. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Transcribed image text: Bond's formula is a useful tool when comparing crushing applications as well as grinding applications. In crushing energy calculations, a crushability index (impact work index) as determined by laboratory tests is used. Now consider a certain material being crushed in two different size ranges, a coarse crushing range and a fine crushing range, for the same reduction ...
