SAG Mill Process Control

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

In existing mills, a partial retrofit solution for increasing pulp-lifter depth is to increase the depth of the pulp-lifter channel towards the centre of the mill in a tapered pulp lifter (see Fig. 15). Another approach (for unidirectional mills) is to use pulp lifters with pulp-lifter channel walls (normally at a right-angle to the head, Fig. 13) angled downwards from the grate towards the head (i.e., downwards to the right with .
