The heating procedure takes place inside a rotating kiln where a certain volume of gypsum is added towards the cement mixture to make a high-quality powder.
At the most well liked Section of the kiln, a 1870 C flame heats the raw materials to about 1480 C. Beneath this rigorous heat, a series of chemical reactions converts the partially molten Uncooked product to pellets termed clinker. With the addition of a little number of gypsum, the clinker is floor to an especially fantastic gray powder. It is currently thought of portland cement - All set for shipment to concrete producers after which you can to building websites.
