The power draw consumed by the first chamber is 823.4 kW and by the second chamber is 1.495 MW for a total power draw for the mill of 2.32 MW. This prediction is within the expected range for such a mill. The exact experimental power draw is not available for this mill with this ball size distribution and fill level.
