Method and apparatus for the heat treatment of fine-grained material |
摘要 |
The invention relates to a method and apparatus for the heat treatment of fine-grained material wherein a precalcination zone formed by the kiln exhaust gas duct of a rotary kiln and into which two branch streams of cooling air which have been subjected to opposing rotational flow are introduced. In this way an equalization of the speed profile over the cross-section of the kiln exhaust gas duct and an improvement in the burning up of the fuel is achieved.
