ABSTRACT:
A process for drying moist material, particularly substances containing water of crystallization, in which the material is passed in counterflow through a shaft to gases having an inlet temperature of 200.degree. to 1000.degree. C. The gas rises at a velocity of 2 to 30 m/sec. and the moist substances are introduced into the shaft in a high-density stream so that the moist materials agglomerate concurrently with the drying.
