The development of coal gangue dryer has played a significant role in the reuse of coal gangue. Coal gangue is a kind of mining solid waste. Every year, a large amount of coal gangue is discharged in China. The accumulation of coal gangue will cause great pollution to the surrounding environment, which is very serious.
The treatment or reuse of coal gangue is an urgent problem to be solved. There are several ways to use coal gangue:
1: Recovery of useful substances in coal gangue. Pyrite can be obtained by screening some coal and inferior coal from coal gangue through some beneficiation processes. Both coal and pyrite can be used for their own use.
2: Can be used to generate electricity. The main use of power generation is the washing of coal and washing and mixing to generate electricity, that is, thermal power generation. The burned waste can also be used for bricks and cement.
3: You can make materials for the building. The material that we usually use for bricks is clay, which can replace clay. Moreover, when burning bricks, there are a lot of combustibles in the coal gangue itself, which can also save coal, which is of great help to the cost reduction.
Of course, coal gangue has other functions. Because coal gangue generally contains a lot of water, coal gangue can not play various roles without removing water. Although coal gangue dryer only reduces the moisture of coal gangue, this is The most basic and indispensable, without this step, there will be no future.
The current society advocates environmental protection and sustainable development. The use of coal gangue is a reflection of environmental protection and sustainable development.
