Parametric Studies Of Cement Production Processes

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.
