The Cement Manufacturing ProcessAdvancing Mining

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay to a fine powder called raw meal which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process the chemical bonds of the raw materials are broken down and then they are

Cement Manufacturing Process Phases Flow Chart

Aug 30 2012 · Cement Manufacturing Process Phase IV Kiln Phase. 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.
