The essentials of electrical systems in cement plants | EEP
Average kWh/ton of material ground = 2608/150 = 174 kWh. Power consumption per ton of clinker with a conversion ratio for consumption 1.55 : 1 = 17.4 x 1.55 = 27 kWh/ton. Using 4% gypsum – 1 ton clinker = 1.04 tons of cement. Therefore power consumption per ton of cement = ~26.0 kWh.
