Coal gangue is a kind of solid waste discharged from coal mining and coal washing. It is a kind of black-gray rock with lower carbon content and harder than coal. In real life, if the gangue has not been treated by
crusher and other equipment, it will seriously damage the environment. From the point of view of coal mining, China produces 100 million tons of coal annually and discharges about 14 million tons of gangue. From the point of view of coal washing and processing, 20 million tons of gangue will be discharged per 100 million tons of coking coal washed, and 15 million tons of gangue will be discharged per 100 million tons of power coal washed. From these data, we can see that the discharge of coal gangue is huge.
A large number of piled coal gangue not only occupies land and affects the ecological environment, but also pollutes the surrounding soil and groundwater by leaching water of coal gangue. Coal gangue contains certain combustibles, which occurs naturally under suitable conditions and pollutes the atmosphere by discharging harmful gases, affecting the health of residents in mining areas. Therefore, the treatment of coal gangue is imperative.
It is understood that coal gangue is mainly used in the production of gangue cement, concrete lightweight aggregate, refractory bricks and other building materials. In addition, it can also be used to recycle coal, coal and gangue for power generation, and can be made crystallized aluminum chloride, sodium silicate and other chemical products. All of these re-utilization of coal gangue involves mechanical equipment, without which the deep processing of coal gangue can not be completed, let alone turning waste into treasure.
Whether it is used to make bricks, cement additives or coal gangue power plants, the processing equipment used is jaw crusher, impact crusher, grinder, vibrating screen, feeder and so on. Guilin Mining Machinery Co., Ltd. is a special
coal gangue crusher with unique design and simple operation. It is more effective for individual users and small and medium-sized enterprises to invest. For the treatment of coal gangue, we should also choose which equipment is more suitable according to the specific situation and requirements.
In recent years, coal gangue is no longer only regarded as a huge amount of solid waste. It is also a new resource, which has been widely used in chemical industry, building materials, metallurgy and other fields. At the same time, the corresponding crushing treatment equipment -
mine crusher, has also been widely concerned!
