Autoclave (Alpha Hemihydrate) The chemical structure of alpha gypsum (CaSO4 + 1 / 2H2O) is the same as the beta plaster. There are differences in crystal structure resulting from the production process. For the production of alpha plaster high pressure autoclave kiln is used. Autoclave is a word of Greek origin and means self-locking.

The two plants produce beta-hemihydrate (stucco) or high-temperature plaster. Back in 2006, Grenzebach already supplied the first flash drying system to Pińczów, designed for processing 100 per cent FGD gypsum at a rated output of 480 tonnes of dihydrate per day.
