Gangue mill gangue comprehensive process to help

Coal gangue is one of solid waste and emissions from coal washing process, is in the process of coal into a low carbon content associated with coal, hard coal than the dark gray rock. In recent years, with the further development and application of coal resources, coal gangue waste more and more, according to statistics, China's accumulation has reached 10 million tons of coal gangue, coal gangue and 100 million tons per year will be discharged. Large accumulation of coal gangue, not only take up a lot of land, but also pollute the surrounding soil and groundwater resources, seriously affecting the health of surrounding residents. Comprehensive utilization of coal waste has become a real problem for the community to pay close attention. According to experts, gangue and not simply disposed of as waste, coal and other substances it contains, the gangue crusher, after gangue crusher vertical roller mill , thermal power plants can continue to be used and new building materials, industrial products production. So not only can effectively avoid the problem of environmental pollution caused by coal refuse pile, but also improve the utilization of the waste of resources, both. In the comprehensive utilization of coal gangue in the process, crushing, grinding is an indispensable part of the two. In the broken links, you can choose, cone crusher or impact crusher to break into chunks of gangue materials less than 40mm; then, after crushing the small pieces of material fed into the mill parts to fine processing, in this session, Dawn Heavy Industries to develop and produce vertical roller mill (vertical mill), the European version of the mill, overpressure vertical roller mill and other equipment are used, they can be ground to 80-425 mesh gangue, Furthermore, as admixtures, cement clinker is applied, roadbed material, fired brick, wall materials and other new building materials production, good performance, solid building materials market.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands
