ABSTRACT:
An installation for the manufacture of cement in a rotary tubular kiln comprises a combustion chamber upstream of the kiln, two preheaters for the raw material, one of the preheaters receiving hot gases from the kiln and the other preheater receiving combustion gases from the combustion chamber, and a cooler receiving the clinker from the kiln. One of the preheaters is a multi-stage preheater and all of the raw material is introduced into the one preheater one of whose stages is arranged to divide the raw material into two fractions. One of the raw material fractions is passed sequentially into the other preheater and into the combustion chamber while the other fraction is passed sequentially into the other stages of the one preheater and into the combustion chamber.
