Pyroprocessing is an important stage in cement manufacturing. In this process, materials are subjected to high temperatures so as to cause a chemical or physical change. Its control improves efficiency in energy utilization and hence enhances production for good quality assurance. Kilns used in cement manufacturing are complex in nature.

Once the clinkers are cooled, they are ground to a powdered form in tube mills. At this stage, a minuscule quantity (2-3%) of gypsum is added to the mix to coat the cement particles and retard the setting of cement. The desired cement powder is ready and is finally packed and transported. Fig.: Rotary kiln.
