Energy optimization in cement manufacturing Reprint from ABB Review 2/2007 Cement producers are large consumers of thermal and electrical energy, which on a global level are only available at steadily increasing costs. Efforts to reduce demands by using higher effi ciency equip-ment and substituting fuels and raw materials to lower production
Morethe energy used is in the form of fuel for the production of cement clinker and electricity for grinding the raw materials and finished cement. Thermal energy accounts for about 20–25% of the cement production cost [10]. The typical electrical energy consumption of a modern cement plant is about 110–120 kWh per ton of cement [11].
