[0002] When processing cement, it needs to go through processes such as crushing, pre-homogenization, raw material preparation, preheating and decomposition, cement clinker burning, and cement grinding. During the burning process, the solid waste discharged from the cement kiln is slag. The amount of discharged slag is very large and should be comprehensively utilized. Slag can be made into cast stone products, slag bricks or blown into slag wool for thermal insulation. Slag can also replace sand and gravel as ballast. Slag has been widely used in various fields of industrial and agricultural production in the world. Before being recycled, the slag often needs to be crushed for easy transportation and processing.
