Electric motors will only draw as much power as the crusher needs. However, the theoretical difference in a 500,000-ton quarry or mine is about 90,000 kW/hours. That reflects only the primary crusher, not the added power it takes downstream to also recirculate 30% more rock through the secondary circuit.
