Classification System Efficiency – A Comprehensive …
Comparison of the ball mill feed and product size distributions in grinding circuits with low and high circulating load ratios led to the understanding that having a high percentage of coarse solids in the grinding mill is directly related to how well the classification system is performing (McIvor, 1988a).
Ball Mill Circuit Classification System Efficiency
— Coghill and deVaney (1938) also conducted experiments in a pilot plant ball mill closed circuited with a rake classifier over a wide range of circulating load ratios. They noted that, "It held true that the percentage of decrease in mill capacity was almost identical with the percentage of finished material in the composite feed.
