based on bonds crushing law the power required to crush a certain material will change by if the diameter of the product is made smaller by 50 in crushing a certain ore the feed is such 80 is less than 508 mm in size and the product size is such that 80 is less than 635 mm
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
