These models were developed to decide, for example, a reduction in the feed size to increase the ball charge at the same power as a way to increase the SAG mill throughput. As has been stated by Powell et al., 2001, for high mill loads, it is possible to increase mill throughput by changing the load conditions increasing the ball charge.
