Abstract
Process for producing cement clinker with improved dust recovery. g cording to this process an inorganic filler passes through an exchanger, a furnace and a quenching zone, while a derived stream is subjected to cooling and to dust removal, which dust removal is made easier by the incorporation of clinker dust in the derived stream, so that deposits in the exchanger are avoided. This process makes it possible to produce a clinker of good quality with a reduced pollution of the environment.
