Reduction Ratio

Bond proposes an optimum reduction ratio for rod mills [BON 61b p 545] If the real ratio deviates then W i must be multiplied by a correction coefficient (equation 26 in [ BON 61b p 545]) For a ball mill if the reduction ratio becomes less than 3 (target grinding of concentrates) the energy index W i must be multiplied by a given
