chemical reaction in cement kiln

Aug , kiln is a huge rotating furnace also called as the heart of cement making process here, raw material is heated up to c this temperature begins a chemical reaction so called decarbonation in this reaction material like limestone releases the carbon dioxide high temperature of kiln makes slurry of the material
