Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).
Another factor that allowed the milling process to be more efficient was the decrease in the circulating load. Depending on the decrease in circulating load, rate of material flow through the ball mill was reduced and retention time was increased.

The summary results of the four tests are given inTable 1Test 3 simulates a ball mill in closed circuit with high fre quency screens, which typically have in the order of 100 per cent circulating
the ball mill for regrinding, along with the raw or new feed stream. In this process, a circulating load of 300 to 350 percent was the accepted norm. In other words, the amount of material circulating back to the ball mill was 3 to 31/2 times the amount of new feed added to the mill! Exploring the use of
ore per day in six overflow ball mills. The concentrate is transported to a smelter a few miles away. The crushed ore from primary and secondary ores is conveyed into bins. The ore from the bins is fed into the ball mill using a conveyor belt. The ball mill grinding circuit is illustrated in Figure 2. % Solids 78.9 Circulating Load 474% Advance

CONCLUSION The circulating load and classifiion efficiency can have a significant effect on the performance of both closed ball mill and HPGR circuits. This is a wellknown 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.
