Abstract
Process for the production of calcined gypsum, by feeding the raw gypsum, in a finely divided state or in pulverulent form, to a hot gaseous stream, characterized in that the raw material, in a margin of relatively small or relatively large granulometry, is it feeds into a tank-shaped treatment chamber, in which it is brought into contact with a hot gaseous stream conducted from bottom to top, whereby the raw material moves, essentially in suspension, towards the bottom, in countercurrent with the hot gas, and then the material is fed to one or more subsequent dehydration hoppers.
