Method and apparatus for producing cement clinker

摘要: The invention relates to the production of cement clinker from powdered and fine-grained raw material using a cyclone preheater, precalcination arrangement, kiln cooler. In order that fine dust filtered out exhaust gases preheater can also be reliably preheated, precalcined then burned in kiln, after first stage smaller part-quantity is branched off fed jointly with total filter upper end this mixture passes through arrangement top bottom, guided co-current air for combustion and, fuel being delivered, thereby introduced into inlet.
