The invention discloses an admixture for cement clinker production, which belongs to the technical field of building material admixtures. The admixture of the present invention is composed of the following raw materials in percentage by weight: 1-5% ferric chloride, 1-10% ferric sulfate, 5-10% urea, 3-5% glycerin, 5-10% compound sodium sulfate, nitric acid Ammonium 5-10%, the balance is water. The combustion efficiency and the quality of cement clinker can be effectively improved by adding 1.4-1.6‰ of the additive of the present invention to the coal pulverizer. The admixture of the present invention, urea and ammonium nitrate act as a denitrification aid for forging, glycerin acts as a grinding aid to increase heat, ferric chloride catalyzes the calcination of cement clinker, and in addition, sodium sulfate and modified boron nitride, the two synergize, Jointly achieve the purpose of energy saving, emission reduction and efficiency increase, obtain high-strength cement clinker, and at the same time achieve the technical goals of accelerating firing speed, increasing production, saving coal consumption, fixing sulfur and denitrification, and reducing costs, which has broad economic and social benefits.
