METHOD AND APPARATUS FOR DISPOSING OF WASTE DUST GENERATED IN THE MANUFACTURE OF CEMENT CLINKER

摘要

A method of disposing of undesirable chemical compounds in waste dust (90) generated in a first kiln (84) in the manufacture of cement clinker by using the dust and slag (96) as the feedstock material to a second kiln (94), heating the feedstock material in an oxidizing atmosphere, and raising the heat sufficient to diffuse the waste dust and the slag to form a hydraulic product such as cement clinker and lime but insufficient to volatilize previously precipitated chemical compounds in the feedstock material.
