摘要

Perfections in devices for the continuous transformation of hydrates of halogen salts in the anhydrous form, where the hydrated humid, in a; first stage, it is previously calcinated by heating under strong agitation until all the surface water, and a part of the water of crystallization have been separated, after which the previously calcined product in several stages and in carefully moved bed is heated until it has reached the temperature necessary for the final calcination by continuously removing the vapors released by the dry gas, introduced under pressure to keep the bed swirled; characterized in that the device shows as a first stage a fast dryer, such as a current dryer composed of at least one tube with a dust separator arranged next and a return line, an indirectly heated calcination furnace being connected as subsequent second stages each time., in which by blowing a dry gaseous medium, preferably pressurized air, the product is kept in a swirling layer and the water vapor that is formed is continuously removed.
