Energy consumption in cement production o ~ 2 % of the global primary energy, or 5 % of global industrial energy, is consumed in cement production, of which: 85 - 90 % is thermal energy 10 - 15 % electricity; o ~ 25 % of cement cost is due to energy costs, of which: o ~ 50 % is for electricity, mainly for grinding.

The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding, both raw and cement.

Jun 01, 2015 As result, for each 1500-kW raw material grinder and 3500-kW cement grinder, the amount of energy saved due to reduction in energy consumption was about 6.3 kJ/(kg cement) and 11.6 kJ/(kg cement) per year, respectively. On the other hand, the increase in production capacity means that the time which the grinders are needed to be in operation ...
