The cooled clinkers are received from the cooling pans and sent into mills. The clinkers are grinded finely into powder in ball mill or tube mill. Powdered gypsum is added around 2-3% as retarding agent during final grinding. The final obtained product is cement that does not settle quickly when comes in contact with water.

When gypsum is heated at about 150–160 °C, it loses approximately three-quarters of its water in a partial dehydration process and becomes hemihydrate gypsum (CaSO 4 •½H 2 O) or calcined gypsum; it is also known as beta gypsum (alpha gypsum is made by processing batches of gypsum under elevated pressure). Calcined gypsum or …

gypsum were dried first at 150°C to remove excess moisture (anhydrous gypsum) as they tend to form lumps when wet and thereafter grounded to a fine powder. Nitrogen gas (50ml/min) was passed through the reaction tube as an inert gas in the furnace. Reaction products from the furnace were allowed to cool in a nitrogen atmosphere.
