ABSTRACT:
An apparatus for effecting the thermal conversion of gypsum to calcium sulfate hemihydrate includes a reactor having a series of fluidized bed compartments containing separate heat exchangers and defined by partitions each provided with an opening which is selected so that the material undergoing treatment progresses, without return movement, through the series of fluidized bed compartments. The apparatus is further constructed so as to permit recycling of fine gypsum particles from the outlet to the middle of the reactor.
