Relates to the technical field of cement production, and provides a process for producing cement by comprehensively utilizing solid waste, which comprises the following steps: step 1, firstly, carrying out preliminary crushing on the solid waste to obtain preliminary solid waste particles; wherein the maximum diameter of the primary solid waste particles is smaller than or equal to 4 mm; and 2, drying the obtained preliminary solid waste particles, so that the water content in the solid waste particles is less than 1%. According to the invention, through preliminary crushing, solid wastes are crushed, and unavailable substances in the solid wastes are all removed, so that preliminary solid waste particles are in a clean state. In order to improve the particle size of the ground material, the moisture of the solid waste needs to be controlled below 1%, so that the pulverizing efficiency is higher. Meanwhile, through specific crushing equipment, mutual aggregation and caking of fine particles in the process that the specific surface area of the materials is gradually increased are avoided, and the crushing quality is improved. Finally, the proportion of the powder solid waste in the cement raw material is higher.
涉及水泥生产技术领域，本申请提供了一种综合利用固体废物生产水泥工艺，包括以下步骤：步骤一：首先对固体废物进行初步粉碎，获得初步固废颗粒；其中，所述初步固废颗粒的最大直径为≤4mm的颗粒；步骤二：对所得的初步固废颗粒进行烘干，使得所述固废颗粒中的含水量＜1％。本发明，通过初步粉碎，将固体废物进行粉碎，再将其中的不可用物质全部剔除，从而使得初步固废颗粒的处于洁净状态。为提高研磨物料的粒度，要将固体废物的水分控制在1％以下，以使制粉效率更高。同时，通过特定的粉碎设备，避免在物料比表面积逐渐增大的过程中出现细微颗粒相互聚集、结团，提高粉碎质量。最终，使得粉料固废物在水泥原料中的占比更高。
