    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. Underground mines are an example the hoisting capacity of the mine shaft is the rate-limiting step in the process and the SAG mill must adapt to
