Electrical Energy Management in the Cement Industry

A cement plant uses about 150 kWh of electrical energy per metric ton of cement produced. Where is this electrical energy being used? How is it being used? Can it be utilized more effectively? If so, how? What can be done to conserve the electrical energy used in an existing cement plant and in future cement plants? An electrical energy management program to resolve these questions is presented. Included is an electrical energy consumption survey of five cement plants. Department consumption is tabulated, and suggestions are made to conserve electrical energy and reduce cost of electrical power in both new and existing plants.
