Gangue is one solid wasted material in the process of coal exploration and coal washing, and this material is owing the lower-carbon percentage, whose color is black and grey. Gangue will cause the serious environment pollution and destroy the surrounding living situation if this kind of material is not being processed by some crushers. Every years 100 million tons of coal are being produced by China, and the amount of gangue can reach 14000 thousands ton, so we can see from the data that the power of gangue is enormous.
The stacking and storing of this amount of gangue not only will occupy the land, but also can influence the ecological environment while affecting the surrounding soil and groundwater, so to solve the problem of gangue must be done in a short time.
Crushers and sand making machine have been widely used in processing gangue, and this material can be applied in cement making, brick making, powder making factory and so on, and some machines being used in this process include jaw crusher, impact crusher, adjustable crusher, vibrating screen, feeder and so on.
People has begun to change this mind on the gangue, thinking it is not the solid wasted materials any more, on the contrary, it is one new energy, and this kind of material is being widely used in the following fields such as the chemical, building material, metallurgy while some crushers that being used to process also get a lot of attention.
