Calcination is the process of calcium carbonate decomposition into calcium oxide (CaO) and carbon dioxide (CO2), typically occurring at a temperature around 850-900°C. As the calcination is an endothermic reaction (~1.7 MJ/kgCaCO3), fuel is combusted in the calciner. In the rotary kiln, the remaining calcination is completed and clinker is formed.
