Method and device for stabilization, cooling and dehumidification of stucco

In a process for the continuous conditioning of plaster of Paris it is supplied in the form of particles from an upstream calcining a stucco cooler. In the stucco cooler soluble calcium sulfate anhydrite to calcium sulfate hemi-hydrate and calcium sulfate dihydrate initially be converted to calcium sulfate hemi-hydrate and crystalline defects healed. Subsequently, the stucco is brought into contact with ambient air and dehumidified by this and thereby simultaneously indirectly cooled.
