Cement clinker and preparation method thereof
The invention provides a cement clinker and a preparation method thereof. The preparation method comprises the following steps: mixing high-iron bauxite powder, a carbon reductant, hydrated limes, an organic binder and water to obtain a mixture; preparing the mixture into a pellet; drying the pellet; directly carrying out reduction and melting separation on the dried pellet; cooling the pellet, and carrying out self-pulverization on the pellet to obtain powder; sieving the powder to obtain grained irons and first self-pulverized reducing slag; and carrying out magnetic separation on the first self-pulverized reducing slag to obtain grained irons and second self-pulverized reducing slag which serves as the cement clinker, wherein based on the total weight of bauxite powder, the carbon reductant and the hydrated limes, the weight percentage of the bauxite powder is 54.55-56.93 percent, the weight percentage of the carbon reductant is 10.81-11.28 percent, the weight percentage of the hydrated lime is 31.79-34.64 percent, the weight of the organic binder accounts for 2-4 percent of the total weight of the bauxite powder, the carbon reductant and the hydrated lime, and the weight of the water accounts for 7-9 percent of the total weight of the bauxite powder, the carbon reductant and the hydrated lime.
