Title:
セメントクリンカーの製造方法及び装置
Document Type and Number:
Japanese Patent JP3730262
Kind Code:
B2
Abstract:
The invention relates to the production of cement clinker from powdered and fine-grained raw material using a cyclone preheater, a precalcination arrangement, a kiln and a cooler. In order that fine dust filtered out of the exhaust gases from the preheater can also be reliably preheated, precalcined and then burn to cement clinker in a kiln, after the first preheater stage a smaller part-quantity of the material is branched off and fed jointly with the total fine dust from the filter to the upper end of the precalcination arrangement, and this material mixture passes through the precalcination arrangement from top to bottom, is guided in co-current with air for combustion and, with fuel being delivered, is thereby precalcined and then introduced into the kiln inlet.
