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.
