impact crushing work index of granite Aggregate Crushing Value Test Determine Aggregate Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material

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 kWht 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
