SAG Mill Process Control - Grinding & Classification

There is a type of plant where the constant throughput SAG mill is sensible If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere
