Coal gangue is a kind of solid waste discharged in the process of coal mining and coal washing. It is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal formation. It includes the gangue in the process of roadway excavation, the gangue extracted from the roof, floor and interlayer, and the gangue extracted from the coal washing process. Its main components are Al2O3 and SiO2. In addition, it also contains Fe2O3, Cao, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium and cobalt).

The coal gangue crusher is also known as the equipment for fine crushing (the coal gangue hammer crusher is mainly used for crushing the coal slag, slag, shale, coal gangue, construction waste and other materials in the brick and tile factory, solving the problem of using gangue and coal slag as the additive and internal fuel in the brick factory, and using gangue and shale to produce standard bricks and hollow bricks with high moisture content.

The coal gangue crushed by the coal gangue crusher can be used to manufacture unburned hollow brick: no fuel is used to burn bricks, energy is saved; no (less) land is used to make bricks, good source of land is saved, waste is turned into treasure, environmental pollution is reduced, and the construction of the plant is well invested, and the enterprise benefit is high. It is a new product vigorously advocated and promoted by the national environmental protection department. At present, using gangue and coal cinder as additive and internal fuel for brick factory, and using gangue and shale to produce standard brick and hollow brick has been an important measure that conforms to the policy and benefits the society.

With the development of technology, gangue is no longer a kind of industrial waste The simple waste, but the secondary good source coal gangue that can be used, can be divided into direct utilization type, quality improvement processing type and comprehensive utilization type. It is the inevitable choice for the sustainable development of modern coal mines to strengthen the comprehensive utilization of good source coal gangue, enhance the awareness of environmental protection, improve the economic benefits, save and intensive good source
