| description | A method for producing cement clinker and co-producing kiln dust potash fertilizer by using alkali-containing tailings belongs to the technical field of industrial waste resource reutilization, and comprises the following steps: mixing, homogenizing and grinding limestone, tailings, iron ore and other raw materials according to novel dry production requirements by using SiO2 and Al2O3 mineral substances rich in the alkali-containing tailings; and then conveying to a novel dry-process rotary kiln with an alkali removal device for roasting, quenching and grinding to obtain the cement clinker. The method not only solves the problem of comprehensive utilization of alkali-containing tailings in cement and building production, but also widens the source of cement production raw materials, and provides a new way for realizing zero emission of alkali-containing industrial solid wastes.
