Evolution of the cement Process Wet process easiest to control chemistry amp; better for moist raw materials. Wet process high fuel requirements fuel needed to evaporate 30+% slurry water. Dry process kilns less fuel requirements Preheater/Precalciner further enhance fuel efficiency amp; allow for high production rates.
#0183;#32;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 C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.
Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the '' Clinker '' pages.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
Fig: Manufacture of Cement by Dry Process. b) Wet Process The raw materials are firstly crushed and made into powdered form and stored in silos. The clay is then washed in washing mills to remove adhering organic matters found in clay.
