subject: Crusher And Mill Promotes Reutilization Of Coal [print this page] Coal is China's most important energy; it plays an extremely important role in the socio-economic development. Plays a tremendous role in promoting the development and utilization of coal, both socio-economic, but also had a significant impact on the environment. Gangue and coal bed methane is the main waste generated in the coal development process has long been the coal industry as a hazardous material and hazardous gases.
After the Third Plenary Session of the Eleventh CPC Central Committee, with the continuous deepening of economic reform and the healthy and rapid development of China's industry and agriculture, in the case of energy has become scarce, people gradually realized that these wastes are still available for use. In particular, the past two decades, the coal sector in the gangue and coal bed methane development and utilization of a lot of exploration and production test and achieved a number of achievements. Practice has proved that as long as the change concepts, scientific research, according to local conditions attention to the development, secondary use of mineral resources in the process of coal production is not only feasible, but has great potential; not only can transform the harm into turning waste into wealth, and can save energy, and access to major social and economic benefits. Gangue is discharged in the excavation of coal mining and washing process solid waste. Is a mixture of carbonaceous, argillaceous and sandy shale, with a low calorific value. Carbon content of 20% to 30%, some containing humic acid. China over the years has accumulated gangue about 1000Mt, and each year continues to emissions of about 100Mt, not only the accumulation area of, but also the spontaneous combustion of contaminated air or cause a fire.
Recent years, with the rapid rise of industry awareness of comprehensive utilization of coal gangue change waste into treasure? At home and abroad have developed much Utilization. The basic principle is to identify the nature of the gangue on the basis of differential treatment, to make the best use, and all kinds of way to combine together to form a certain scale of development and utilization system to obtain the best value for money. Regardless of the gangue for what channels gangue is a jaw crusher, impact crusher, Raymond mill, Super pressure trapezium mill, vertical mill, European trapezium mill , etc. and processing equipment utilization.
