the load to that of power on load volume for a pebble mill. A two-stage peak seeking controller was thus implemented: first the optimum pebble loading was found (i.e. pseudo peak power) and then the true power peak was sear ched for by making step changes to the water addition rule.

Re-circulating load applies "edges" on rocks to allow SAG to break edges off the parent rock. A little academic exercise - calculate the force needed to break a 2 mm slice off a 25 mm sphere. The tangential loading force at the cross-section has a diameter of 13.5 mm or more than half the rock diameter.
Mar 15, 2019· The circulating load increases from 129 to 134% with coarser feed. In this case, there are opportunities to further increase the circulating load by increasing the hydrocyclone operating pressure to decrease the cut size. This option will produce a finer circuit product size.
All the ore bins are located within the mill building. Ore is reclaimed from the fine ore bins on a 24" wide conveyor operating at fixed speed, feeding a "6.5' x 6' rubber lined Eimco ball mill equipped with a 150 HP motor. The mill has been reported to be operating at a 72% critical speed, with a targeted 300% re-circulating load.
