  • Reduction Ratio - an overview | ScienceDirect Topics

    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 .
