ball-on-shell impacts just above the charge toe, owing to the risk of ball-on-liner damage and excessive metal flow. In fixed-speed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle.
