Techniques for regulating calcining processes, particularly the calcining of lime containing materials, which are supplied as pulverized raw material, into cement clinkers in a cylindrical rotary koln, provides that the exhaust gas preheats the raw material and the calcined material preheats the combustion air. The quantity of raw material and the quantity of combustible material, the temperature of the combustion air and of the exhaust gas, as well as the composition of the exhaust gas, and additional parameters of the process are continuously measured and partially controlled. From the continuously measured individual values of the process a characteristic value describing the condition of the process, particularly the supply of heat, is formed, and is utilized to regulate the calcining process.
