Energy optimization in cement manufacturing
Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further
