    In SAG mill operation the grinding rate passes through a minimum at a "critical size" (Chapter 5) which represents material too large to be broken by the steel grinding media but has a low self-breakage rate. If the critical size material typically 25–50 mm is accumulated the mill energy efficiency will deteriorate and the mill feed
