Coal gangue is a kind of solid waste in the process of coal mining and clean coal production. A large number of coal gangue piles not only occupy the land, but also pollute the ecological environment. However, by processing coal gangue, the waste can be turned into resources. It is now used for power generation, cement production, brick making, production of chemical products, and soil improvement.
Coal gangue is a relatively hard black gray rock. The processing of coal gangue can be divided into three stages: the primary crushing by jaw crusher, the secondary crushing by impact crusher and the sand making and shaping by sand machine. Among them, impact crusher plays a more important role in the process of crushing. It has large production capacity, high production efficiency, less pollution in the process and environmental protection. It is an ideal equipment for the processing of coal gangue.
