Abstract

A process for producing cement clinker according to the invention comprises dry grinding of raw components, mixing the resultant raw meal with a solid fuel, pelletizing the resultant batch with the addition of calcium chloride thereto, subsequently heat treatment of the resultant pellets of a raw mix in their dense layer in zones of drying, roasting by burning a fuel over the surface of the layer with drawing fuel combustion products therethrough and removal of exhaust gases released therefrom, and cooling the resultant clinker. According to the invention, the temperature of fuel combustion products over the surface of the dense pellet layer is maintained at 1150.degree.-1250.degree. C. within a portion of the roasting zone extending over a length of maximum one half of the roasting zone length, with subsequent lowering of this temperature to between 900.degree. and 1000.degree. C. in the direction toward the cooling zone
