Coal gangue is a common solid waste in mine shafts. Long-term stacking not only occupies a large area of root area, but also causes serious pollution to the environment. Therefore, the treatment of coal gangue pollution is imminent, and the pollution control of coal gangue is mentioned, and the mining equipment is indispensable. The crusher, sand making machine, mill, etc., Raymond machine is one of the important ministers in the process of its management.
If coal gangue is piled up for a long time, the first thing that affects direct use is the use of land resources. Although China has a large land and large population, it has a large population. Therefore, land resources need to be used rationally. Secondly, coal gangue open-air stacking will also cause serious air pollution. Weathering will generate a large amount of dust, which will be dispersed into the air under the blow of wind. It will cause serious air pollution to the mines and surrounding households. In severe cases, improper treatment of coal gangue will spontaneously ignite at the point of ignition and will be released during the burning process. A large amount of harmful gases such as sulfur dioxide and carbon dioxide are discharged into the air, which seriously affects the quality of the surrounding air and affects the surrounding ecological environment. It also poses a threat to the health of nearby residents. After that, it will also pollute the surrounding water and soil. In the process of rain washing, in addition to common substances, some heavy metals will also dissolve in the water and flow into the river. If people, animals or crops are misabsorbed, it will cause serious illness or even death; therefore, the treatment of coal gangue is a piece. Very urgent and important, the country, the company and the individual should To pay attention to.
In fact, the utilization value of coal gangue is still a lot. Among them, coal and pyrite are all recoverable resources. After a simple process, coal and pyrite resources can be washed and selected, and coal can be used as a boiler for power generation. The fuel is used for power generation. Pyrite can also be used as raw materials for chemical industry and smelting. Among them, the crushing and treatment of coal gangue cannot be separated from the processing of jaw crusher and [url=https://www.sbm-mill.com/products/mtw-mill.html]raymond mill[/url]. In addition to the reuse of coal and pyrite, coal gangue can also be used as a building material in a large number of building facilities. It can be used as a brick material instead of clay, and can also be crushed and ground into building aggregate. In recent years, the demand for building materials in China's urban expansion is also very large. Coal gangue can be used to replace other building materials and be fully utilized. This can solve the problem of shortage of building materials and prevent random mining of mines. Coal gangue is treated reasonably to solve the pollution problem. Regardless of the material being reused, its processing is inseparable from the mining equipment in the production process.
Raymond machine occupies an irreplaceable position in the recovery and reuse of coal gangue. It is also an environmentally friendly mining machine supported by the state. The pollution treatment of coal gangue cannot be ignored. I hope the relevant departments pay attention to it.
