Independent Researcher. Gypsum is a mineral and is hydrated calcium sulphate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.
Different form of synthetic or byproduct gypsum are now available for use and are being produced at economical rates which help the gypsum producers. In the business of making cement, gypsum costs usually very economical. Synthetic gypsum reduce costs as well as provide other manufacturing, environmental, and political benefits.
Analysis of Pakistani Cement Industry – A Report. HISTORY . Cement industry is one of the few industries that existed in Pakistan before the partition of the subcontinent. The major reason for the existence of this industry is the availability of the raw materials.
The dryer will be used to dry flue gas desulphurisation (FGD) gypsum from a captive coalpower plant for use in cement plants. In the planned dryer plant the moisture of the FGD gypsum will be reduced to a residual moisture of <2%.

Natural gypsum is used in India for manufacturing fertilizer, cement and gypsum board industries. High purity gypsum is earmarked only for the fertilizer industry and poor quality of gypsum (of purity less than 60 per cent) is supplied to cement and gypsum board industries.
Gypsum Rock. The average person eats about 28 pounds of gypsum in a lifetime. When gypsum rock is crushed and the water removed, it can be used to make plaster of paris, commonly used in industry. Ground gypsum is also used as a soil conditioner. Chemically, gypsum rock is calcium sulfate with two molecules of water.
Natural gypsum supply to the cement industries will continue to be around mtpa till 2021. Local phosphogypsum supply. Annual production of phospho gypsum in India is around 6 million tonnes and cement sectors use around 4 5 million tonnes on a yearly basis.
Abstract: A cement company in Alabama replaced their use of natural gypsum with synthetic gypsum as a means to lower its operating costs. But, owed to the difficult material handling challenges associated with synthetic gypsum, experienced severe problems with flow of synthetic gypsum in its feeder bins.
Natural gypsum is used in India for manufacturing fertilizer, cement and gypsum board industries. High purity gypsum is earmarked only for the fertilizer industry and poor quality of gypsum (of purity less than 60 per cent) is supplied to cement and gypsum board industries.
Another major use of gypsum is in the cement industry, where it is added at the rate of 2–5% to cement clinker prior to final grinding to retard the setting rate of concrete. Cementgrade gypsum tolerates higher NaCl (–% maximum) and insolubles (6% has been used).
