VALIDATION OF A CLOSED CIRCUIT BALL MILL MODEL Alex,

Closed ball mill – cyclone circuits are industry standard and it is recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding. The individual effect of circulating load and classification efficiency is difficult to quantify in practice as these two parameters are inherently interrelated. Even though mill capacity,Closed Circuit Grinding VS Open Circuit Grinding,Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter.
