Abstract
In a process for the continuous conditioning of gypsum plaster, the gypsum plaster is passed from a calcination facility connected upstream to a gypsum plaster cooler in the form of particles. In the gypsum plaster cooler, soluble calcium sulphate anhydrite is initially converted to calcium sulphate hemi-hydrate and calcium sulphate dihydrate to calcium sulphate hemi-hydrate, and crystal defects are eliminated. Subsequently, the gypsum plaster is brought into contact with ambient air and dehumidified by the latter and thereby simultaneously cooled indirectly.
