Austin et al. (1984) express the connection between specific grinding energy and ball load as follows: "Although the capacity of a laboratory mill is a maximum at 40 to 45% ball load, the relative specific grinding energy m p /SW is a minimum at about 15 to 20% ball load. In practice, ball loads less than 25% are not normally used because low ...
