Calcination in a rotary kiln is a direct, long-time calcining process. During the process, the phases of the CaSO 4 x H 2 O system can be optimally adjusted. Rotary kilns are used for the calcining natural gypsum. In this process, pre-crushed natural gypsum is calcined in parallel flow with the flue gas.

the calcination takes place. 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

However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition. As the most decomposition reaction is endothermic, so the temperature of calcination is generally depends on the transfer of heat into the particle.
