<p>The plant for heat treatment of ground material, especially for the prodn. of cement clinker from crude powder material (10), uses the exhaust gas from a cylindrical kiln (13). The hot bypass dust from a partial gas flow dust extractor (24), at least at the delivery of the coarse grain components (28,29), is passed directly to a hot dust cooler (33) which uses cooling air (32), to be cooled by a direct heat transfer. The channels (39,41,41') to take off the heated cooling air from the hot dust cooler (33) are connected to the partial gas flow cooler (23).</p> |
