Energy Efficiency and Saving in the Cement Industry

Cement production involves the heating, calcining and sintering of blended and ground materials to form clicker. As a result, cement manufacturing is the third largest cause of man-made CO 2 emissions due to the production of lime, the key ingredient in cement. Therefore, energy savings during cement production could lead to lower environmental
