Abstract

Die Erfindung betrifft ein Verfahren sowie eine Anlage zur thermischen Behandlung von feinkörnigem Gut, wobei zur Einstellung der Guttemperatur in einer der Kühlzone (3) nachgeschalteten Heißbehandlungszone (4) dem in der Kühlzone gekühlten Gut ein Teilstrom ungekühlten Gutes zugemischt wird. Dadurch läßt sich auch bei Änderungen der Gut-Durchsatzmenge und Konstanthaltung der Külluftmenge die Guttemperatur in der Heißbehandlungszone konstant halten. The invention relates to a method and an installation for the thermal treatment of fine-grained material, where for setting the product temperature in one of the cooling zones (3) downstream heat treatment zone (4) in the Cooling zone of cooled goods is a partial flow of uncooled goods is admixed. This allows changes to the Good throughput and constant cooling air volume the material temperature in the heat treatment zone is constant hold.
