[0001] The utility model relates to the technical field of crushing coarse tailings of coal gasification slag, in particular to a crushing and grinding device for coarse tailings. Background Art

[0002] With the acceleration of the global industrialization process, the generation of various types of solid waste has increased significantly. Among them, the treatment of coal gasification slag has become an urgent problem to be solved. Coarse tailings of coal gasification slag are the products of coal gasification slag after being processed by slag scooping machine. They are mainly large-particle silicon-aluminum components. The stacking of coarse tailings not only occupies a large amount of land resources, but also may cause pollution to the environment. Especially when stored in the open air, it is easy to generate dust, leachate and other problems.

[0003] Therefore, in order to further extract and utilize the industrial solid waste - coal gasification slag discharged in the coal chemical industrial park, the coarse tailings of the coal gasification slag are crushed and ground to obtain coarse tailings powder, which is convenient for using the coarse tailings to prepare various building materials (such as concrete admixtures, concrete fine aggregate), mesoporous materials, silicon fertilizers and soil conditioner materials. A coarse tailings crushing and grinding device is proposed. Utility Model Content
