Calcination; after crushing process gypsum size is reduced to 0-8 mm. Sized gypsum feeds the kiln regularly by weighing belt. Gypsum moves through to the kiln depending on inclination and rotation of the kiln then calcined products come out. To reduce size of the calcined grains is transferred to grinding and classification steps.

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.
