28/01/2019· The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore. The ball load can also be used to shift work from the primary to the secondary mill; a greater load of large balls results in increased impact breakage, and may produce a coarser discharge from the SAG mill.
