The majority are raw meal and cement mills, designed as either vertical or ball mills. Cement production runs continuously with very limited reserve capacities and little redundant plant or equipment. The greater part of the equipment therefore has to run around-the-clock or – if there are specific restrictions – throughout the day.

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
