ABSTRACT:
Method and apparatus for burning raw materials in the production of clinker from cement raw materials in which a portion of the cement raw materials are dried and partially deacidified under conditions which produce granules, while another portion of the raw materials in the form of finely divided meal is heat treated in a suspension type heat exchanger, and at least partly deacidified in a calciner forming part of the heat exchanger. The thus treated granules and meal are then mixed together and the mixture is treated in a thermal reactor such as a rotary kiln to complete deacidification and to cause the formation of the cement clinker.
