2018年6月24日 The critical speed for this mill was 54 revolutions/minute. For most steady-state conditions examined there is no creation of a water pool (which is typical of overflow mills) at the toe of the ball charge. The immediate observation when a slurry is fed into the mill is a very significant reduction in the noise emitted from the mill.

SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range. Typically a SAG mill weight measurement, by either bearing pressure transducers or load cells, is used as an inferred measurement of volumetric filling. To maintain volumetric filling within a set operating range the SAG weight setpoint use for process control
