Coal preparation serves several purposes. One important purpose is to increase the heating value of the coal by mechanical removal of impurities. This is often required in order to find a market for the product. Run-of-mine coal from a modern mine may incorporate as much as 60 percent reject materials.
Air pollution control often requires partial removal of pyrites with the ash to reduce the sulfur content of the coal. Ash content often must be controlled to conform to a prescribed quality stipulated in contractual agreements. Because of firing characteristics, it is often as important to retain the ash content at a given level as it is to reduce it.
Freight savings are substantial when impurities are removed prior to loading. Finally, the rejected impurities are more easily disposed of at the mine site remote from cities than at the burning site, which is usually in a populated area.
Coal is one of the most important energy, which plays an extremely important role in social and economic development. Development and use of coal, both played a huge role in promoting socio-economic, but also had a significant impact on the environment. Coal gangue and coal bed methane is the main waste generated in the development process which has long been regarded as hazardous substances and hazards gas in the coal industry. Coal gangue is discharged as solid waste in the tunneling, mining and washing process which is a mixture of carbon, clay and sandy shale, with low heat value.
As professional coal crushing plant manufacturer and services provider, experts have researched several years about improving coal crushing efficiency and therefore reducing the waste substances and gas. For coal crush, jaw crusher has been widely applied for coal primary crushing. If needed secondary crush, there are cone crushers, hydraulic cone crusher for your choice. Also, impact crusher is popular as tertiary crushing. After crushed by impact crusher, final products will be of cubic even shape.
For coal further grinding, can provide you with coal mill. Coal mill is specially designed for coal grinding. coal mill is kind of vertical structure which has also been widely used in such industries as cement making, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness. coal processing plant
Apart from coal minerals, Crusher and Grinding Mill have also been widely used for lots of other various non-explosive mineral materials crushing and grinding, such as quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, iron ore, copper, iron oxide red, and zircon slag, cement clinker, activated carbon, dolomite, granite, garnet, iron oxide yellow, fertilizer, compound fertilizer, fly ash, coal, Ling U.S. sand, chromium oxide green, gold, red mud, clay, kaolin, coke carbon, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, stone, shale, basalt, gypsum, graphite, silicon carbide, thermal insulation materials, etc. coal crusher
