optimum choice of the make-up ball sizes for maximum

Sep 01, 2013 · For a single size of make-up ball, the mass fractions in the mill within the size ranges are calculated from: (11) m k = d k u 4 − Δ − d k l 4 − Δ d max 4 − Δ − d min 4 − Δ where d k u and d k l represent the upper and lower boundaries of the ball size interval k, d max is the largest ball size in the mill, and d min is the smallest ball size in the mill which is still retained. Δ is a constant, which relates to wear
