Method and apparatus for the thermal treatment of moist, granular materials utilizing at least two superposed cyclone separators, with a relatively long gas conduit connecting the lower cyclone separator to the upper one. Charging means are provided in the conduit for introducing material to be treated near the lower cyclone separator, and a venturi-type constriction is provided in the conduit below the charging means, the constriction having its lower end projecting into the lower cyclone separator and serving to break up lumps of material which might otherwise be deposited in the cyclone separator and transfer the particulate material to the upper cyclone separator.
