Grey relational analysis of grey system theory was applied to study the relationships between the heat consumption of clinker and production process parameters which base on the actual data of 2500 t / d clinker production of a company, and discuss the ways of new dry process cement technology optimization and energy-saving technologies, and then the industry practice and optimization were implemented.The results showed that the degree of relation between the clinker heat consumption of clinker and production process parameters is high which was analyzed by grey relational.Without sacrificing output and quality of clinker to reduce heat consumption of clinker by oPtimizing ingredients of the clinker proportioning, reducing the pulverized coal ash, reasonable controlling the parameter of clinker firing system, improving the residence time of material in precalciner to reduce incomplete combustion degree of coal and improving the decomposition rate of materials and others integrated approach.After industry practice and optimization,the heat consumption of clinker decreased about 7.36% and the clinker production capacity (tpd) increased about 22%, which showed that grey theory has an important guiding significance for the optimization and improvement of production line system.
