A crusher was used to crush a material with a feed size of 508 cm 381 cm and the power required was 373 KWton The screen analysis of the product was as followsWhat would be the power required to crush 1 tonh of the same material from a feed of 444 cm 381 cm to a product of average product size 0051 cm Use Rittinger’s law
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
