    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
