Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. 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.
