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
