摘要：
CaCO3 is the main component of the raw materials powder mixture to obtain Portland cement. In the clinkerization process, with increasing the working temperature, physico-chemical processes take place in the raw materials, the most important being the endothermal process of CaCO3 decomposition. Thermal efficiency of the plant is given by decarbonization degree of raw materials at feeding rotary kiln. It is proposed a mathematical model for correlation decarbonization degree with the main parameters (temperature, time, granulometric characteristics of the raw materials).
