For instance, at Lornex Mining, one of the most successful SAG installations, the ball load varies normally from 6-7% by volume of the mill; the ball make-up consists usually of 80% 4-inch diameter balls and 20% 5-inch diameter balls. The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore.
