    The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example the finer the grind sie desired the higher is the kWht required to grind to that sie. Magdalinovic 38 measured the Bond work index of three ore types using different test screen sies. He produced a correlation between the mass of test screen undersie per revolution G and
