<p>In a method for continuously conditioning plaster of Paris, the plaster of Paris is fed from an upstream calcining system to a plaster-of-Paris cooler in the form of particles. In the plaster-of-Paris cooler, firstly soluble calcium sulfate anhydrite is converted to calcium sulfate hemihydrate and calcium sulfate dihydrate is converted to calcium sulfate hemihydrate and crystal defects are remedied. Then the plaster of Paris is brought in contact with ambient air and dried by the ambient air and at the same time indirectly cooled.</p> |
