Gypsum Calcining

Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly. Anhydrite .

Grinding and calcining of gypsum with Pfeiffer grinding .

When gypsum is calcined in an atmosphere sat­urated with water vapour at an overpressure of several bars, a-hemihydrate is formed (Fig. 1). The outstanding feature of this plaster is a relatively regular crystal form.

Grinding and calcining of gypsum with Pfeiffer grinding plants

Thanks to the relatively high temperature level in the gypsum calcining mill, the gypsum is simultaneously calcined. When gypsum is calcined in an atmosphere sat- urated with water vapour at an overpressure of several bars, a-hemihydrate is formed (Fig. 1). The outstanding feature of this plaster is a relatively regular crystal form.

Gypsum Calcination - Innogyps

Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.

Features and Benefits - Rapidwall

Gypsum (calcium sulphate dihydrate) is a material that calcines at a relatively low temperature (150°C - 180°C) to produce the required hemihydrate product. The proportions and forms of dihydrate, hemihydrate and anhydrite in the plaster product are very sensitive to calcining conditions, particularly temperature.
