ABSTRACT:
A method for burning fine-grained material particularly for the manufacture of cement clinker wherein a stream of the raw cement meal is sequentially treated at progressively increasing temperatures in a preheating stage, a pre-calcining stage, a calcining stage, and a sintering stage. The improvements involve introducing one or more deacidified raw meal fractions into the stream at one of a variety of possible locations so that recarbonation does not occur.
