Calcination Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2). HighCalcium Lime CaCO 3 + heat CO 2 + CaO Dolomitic Lime ...
Rotary Calciner Applications Calcination. Calcination, often referred to as thermal processing, involves heating a specified material to a specific temperature in order to cause thermal decomposition. For example, in the case of limestone, calcination is used to drive off carbon dioxide. Thermal Desorption
