The invention relates to the technical field of solid waste treatment and recycling, aims to solve the problems of complex formula, various types of added binders, foaming agents, fluxing agents and the like, poor economical efficiency and difficulty in industrial application of a method for preparing ceramsite from solid waste in the prior art, and provides a method for preparing ceramsite from coal gangue and steel slag, and the ceramsite. According to the method disclosed by the invention, the coal gangue and the steel slag are respectively ground and homogenized, and are proportioned according to a certain proportion, the prepared raw material powder is homogenized, granulated, aged, dried, roasted, cooled and the like, and various parameters in each treatment process are strictly controlled, so that various performance indexes of the obtained finished product ceramsite meet the standard requirements, and meet high-strength ceramsite standard requirements; and the gangue and the steel slag are used as raw materials for firing the ceramsite, so that precious clay, shale and other resources are saved, a large amount of solid wastes such as the gangue and the steel slag are effectively utilized, reduction, harmlessness and recycling of the solid wastes are realized, and the ceramsite is suitable for large-scale industrial popularization and application.
本发明涉及固废处置及资源化技术领域，旨在解决现有技术中利用固废制备陶粒的方法，配方复杂，添加的粘结剂、发泡剂、助熔剂等种类繁多，经济性较差，难以工业化应用的问题，提供一种利用煤矸石及钢渣制备陶粒的方法及陶粒，采用本发明所述的方法，将煤矸石和钢渣分别粉磨均化，并按一定比例配料，将配好的生料粉进行均化、造粒、陈腐、干燥、焙烧、冷却等过程，并严格控制各个处理过程中的各项参数，得到的成品陶粒，各项性能指标满足规范要求，达到高强陶粒标准要求，利用煤矸石和钢渣为原料烧制陶粒，节约了珍贵的粘土、页岩等资源，有效利用了煤矸石、钢渣大宗固体废物，实现了固废的减量化、无害化和资源化，适合在工业上大规模推广使用。
