Factsheet on: What is Gypsum?
Gypsum is normally only screened to remove ‘fines’ (mainly mudstones), then crushed and finely ground. Gypsum/Anhydrite for cement manufacture is supplied in crushed form for further fine grinding with cement clinker. C. Processing Natural Gypsum When Gypsum ( CaSO 4,2H 2O) is ground to a powder and heated at 150° to 165° C, The cement grinding plant is a vital link of the finished cement production. The cement grinding plant also called cement grinding unit, is used to grind clinker into qualified cement. With the development of the cement industry, cement grinding plant becomes more common. As an individual section of finished cement production, at this Cement Grinding Plant Overview Cement Grinding Unit AGICO Cement
