摘要 |
Method of producing hemihydrate plaster by calcining natural or synthetic gypsum in at least one cyclone zone, wherein the gypsum and the hot gases are fed into the top of the first cyclone zone and calcining is carried out in a parallel flow of hot gases and particles of the materials to be dehydrated by circulation in a downward direction along a cyclonic path in each cyclone zone, followed by circulation in an upward direction in the central area of each cyclone zone.
