The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen (5), which acts like a large sieve.

The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.

• Use advanced model-based techniques to reduce variation in the feed and thus enable increase in average throughput by operating closer to limits. • Integrate with visual or other rock-classification systems. POWER OPTIMISATION. For the most productive milling operation it is often best to operate close to the maximum mill power draw.
