CONCLUSION The circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and HPGR circuits. This is a well-known fact for ball mill circuits that has been recognised for almost 100 years. For HPGR circuits the knowledge is more recent and is still being investigated.

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.

Apr 01 2013 1. Introduction. Over the years ball mill circuits closed with cyclones have become an industry standard and since the early days it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding i.e. its capacity to produce the desired final product.
Circulating load control The only manipulated variable available in the closed milling circuit ball mill 2 is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density
