    Cement Manufacturing Process Civil Engineering

    Raw Material Extraction/QuarryGrinding, Proportioning and BlendingPre-Heating Raw MaterialKiln PhaseCooling and Final GrindingPacking and ShippingAfter exiting the kiln, the clinker is rapidly cooled down from 2000°C to 100°C-200°C by passing air over it. At this stage, different additives are combined with the clinker to be ground in order to produce the final product, cement. Gypsum, added to and ground with clinker, regulates the setting time and gives the most important property of cement, compressive strength. It also prevents agglomeration and coating of the powder at the surface of balls and mill wall. Some organic substances, such as Triethanolamine (us
