    Ball Mill Circulating Load

    Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill

    increases with increased circulating load ratio, rapidly so at first and continuing to increase more gradually with higher circulating load ratio. The underlying cause of this relationship is revealed by comparing the ball mill feed and product size distributions from two circuits, one with low and one with a high circulating load ratio (Fig. 3).
