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).
