In the manufacture process of cement, clinkers are formed. These cement clinkers are cooled down and added with small amount of gypsum. The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%. Role of Gypsum in Cement
Cement is a mixture of calcareous, siliceous, and argillaceous substances that is used as a binding agent in construction. It is produced through a process involving mixing raw materials, burning in a rotary kiln, and grinding the clinker produced. The manufacturing process can be either dry or wet.
As regards cement manufacture, the process was quite distinctive, with thermodynamics and emissions considerably different from those of traditional manufacturing methods, and the plants were unusually well-described.There were three Anhydrite Process plants in the UK between 1930 and 1976. This article brings the three plants together and ...
