In modern cement plants, cement production is a continuous dry process, where the rotary kiln plays a key role. In the first step raw materials such as limestone, clay, sand, and iron ore are crushed in a cone mill and dried. This raw meal, or slurry, is then fed to a rotary kiln - an enormous rotating pipe - and heated at a temperature of 1.400–1.450°C to become clinker; in the cooling ...

9 Rotary Kiln Processes: With the arrival of rotary kilns, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or "raw meal". 1. In the Wet Process, the kiln system is fed ...

modern cement plant. The 2-base rotary kiln is a statically determined beam system, where the support load is always known. It is a shorter and wider kiln, with a reduced slope to maintain the material retention time, similar to a 3-base kiln. The larger diameter reduces the gas velocity and the dust recircula- tion, and secures a lower burning zone thermal load (Gcal/h/m2) at the same ...

30.08.2012· 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. High temperature of kiln makes slurry of the material. Rotary kiln. The ...
