Processes and apparatus for the heat treatment of fine-grained material, particularly for the production of cement, wherein the material is preheated in a preheater, further heated in a precalcination zone using additional fuel, calcined to completion in a rotary kiln, and cooled in a cooler, the preheated material being introduced into a cooling air stream run off from the cooler and the resulting mixture of gas and solids being introduced from the side into a gas pipe which connects the rotary kiln to the preheater and through which the kiln exhaust gases flow in the upward direction.
