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.
