There are several ways gangue comprehensive utilization: ① coal and pyrite recovery: through a simple process, from coal gangue washed well chosen, by screening to choose the low-quality coal, but picked pyrite. ── shaker or pyrite recovery process from the plane with the jig coal preparation, wash mixed coal and coal. Recovery of coal can be used for power boiler fuel, can be used for washing gangue materials, pyrite can be used for chemical raw materials. ② for power generation: mainly used to wash and wash coal gangue co-firing power. China has been washed and washed coal gangue mixture (heat about 2,000 kcal per kg) boiling furnace combustion for power generation. Slag to produce slag and slag cement bricks. Japan has more than 10 seats this plant; how much the use of a mixture of coal and gangue major gangue grinder, generally every calorific value of 3,500 kcal kg; insufficient firepower with heavy oil combustion. The Federal Republic of Germany and the Netherlands to own power plants and coal preparation plant built together to take advantage of the coal slime and gangue power generation. ③ manufacture of building materials: bricks instead of clay as a raw material, can be less fertile dig. When a large brick gangue grinder, use of coal gangue itself combustibles can save coal. As the leader of gangue grinder manufacturers, three high mechanical strongest vitality lies in technological innovation. Technology innovation is the source for the company's continued development, three high adhere to customer and market-oriented, follow the latest developments in international and domestic technology development of large coal gangue grinder price, and with major research institutes and key institutions to conduct research cooperation, and actively introduce the latest technology and mining machinery equipment, increasing the development of new technologies and the transformation of large coal waste grinder production, forming a "research and development, application and improvement" business development model, the company's technical capacity of the leading level, initially with the technical R & D capabilities. With the innovation of technology, are gradually broken gangue grinder replacement, the company developed the production of shale mill cinder mill, pebble mill, mining crusher, construction waste shredders and other equipment have been gradually reached China's "low-carbon, green" requirements. Gannan Large Large Coal mill Coal mill _ _ how much money is provided by three high mechanical Gongyi City, three high mechanical plant. Machinery Factory of Gongyi City High (www.sangaofsj.com) is specialized in "Coal mill, two-stage crusher, shale crusher, cinder crusher, ore crusher," the enterprise, the company of "honesty, hard service "concept, to provide you with the highest quality products and services.
