    Choosing a SAG Mill to Achieve Design Performance

    A further explanation is required to explain the importance of designing the SAG mill chamber to draw required power at optimum operating conditions of 75% critical speed and less than 30% by volume load. Recent studies in the three foot diameter SAG mill are instructive. The following graph shows the relevant facts as Figure 2.

    The capacity and power consumption of a SAG milling circuit is directly influenced by the size of the feed to the grinding mills and the strength characteristics of the feed material which, during the life of a mine, can show wide variations. These factors, in turn, affect the amount of circulating oversize which must be refed to the SAG mill.
