The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.
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.
