In Efficient Coal Exploiting Crushers As Well As Grinding Mills

The exploration and utilization of coal has played an important role in economy development, but causes great damage on environment.Coal gangue and cbm development are the main wastes.The coal gangue is the solid waste produced during the excavation, mining and washing process of coal.It consists of carbon, shale and sandy shale, and has a low calorific value.The carbon content is 20% ~ 30%, some contain humic acid.They exist in large quantity in countries of rich coal resources, which not only piles up the place and contaminate the environment but also causes fire due to auto-ignition.As energy is increasingly short, people gradually realize these wastes are employable.If the coal gangue can be differentiated and crushed by breakage and grinding equipment, such as jaw crusher, impact crusher, grinding machine, they can be utilized to achieve economic benefit in roughly five aspects: 1).Filling the colliery.The coal gangue can be used as filling materials in underground coal cavity directly or after processing.2).Filling the ground such as road building.3).Generating power.Coal gangue containing rich carbon and high calorific value is used for fluidized bed and circulating fluidized-bed power generation.4).Building materials.The coal gangue is made into gangue brick, cement and lightweight aggregate to act as building materials.5).Extracted sulfur ore or other chemical products from coal gangue and other all these utilizations need crushing by jaw crusher, impact crusher, raymond milling machine, high pressure suspension grinding mill, micro-powder mill.Cone crusher is used for crushing of ores and rocks, the advantages are: reliable structure, high efficiency, easy-to-adjust and economical.The safety spring system is the overload protection device, which makes foreign material goes through the machine without bring any hurt to it.The sealing modes are oil and water, which segregate the stone powder and lubricting system.The crushing chamber is decided by the purpose of ore, the standard model is suitable for medium crushing; the medium model is suitable for fine crushing and the short head model is suitable for fine crushing.Jaw crusher: http://www.Hxjqchina.Com/product-list_11.Htmlimpact crusher: http://www.Hxjqchina.Com/product-list_12.Html.
