difference between ball mill and rod mill ore processing

to that of the ball mill test as follows It is common to observe a difference between the rod mill and ball mill values for a given ore type These differences may be caused by a variation in ore hardness by size 125mm for RWI and 335mm for BWI andor grain size properties The Bond rod mill work index is used to calculate the power
