Manufacturing Process of Cement
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.
