Application of Hongcheng vertical mill in the field of solid waste utilization area

    Annual compound growth rate of industrial solid wastes was 11.54% with the development of industries, according to experts predict that China's industrial solid waste generation will exceed 50 million tons by 2017. Such a huge number passed the signals of larger application space of industry solid waste utilization, according to statistics, 19 are facing a shortage of minerals in varying degrees among China's 54 major minerals, this would mean that comprehensive utilization of solid waste and resource become imminent important strategic initiatives to release the shortage of resources contradictory.

    According to the <<The twelve five-year plan of bulk of industrial solid waste comprehensive utilization and development>>’s statistics, China's industrial solid waste comprehensive utilization rate will reach 54% in 2017, the comprehensive utilization amount will close to 30 million tons, the annual output market value will exceeded 6,000 billion yuan. Therefore, the comprehensive utilization of industrial solid waste situation is grim, but also will further stimulate the escalating mine mill equipment and improvements to the advantage of more efficient, energy-saving, high-yield promote of the comprehensive utilization of industrial solid waste.

    Coal gangue and fly ash are two industrial solid waste and accumulation volume is very large, not only takes up a lot of farmland, but also caused serious pollution of the urban environment and groundwater resources. If we are able to develop high-tech, low-carbon, environmental protection non-metallic new materials industry then to solve utilization of industrial solid waste problem and will be able to reach many gratifying results.

    It is reported that the green bricks made of those two materials has effective use. Pulverized coal gangue and fly ash after mixing with water, is fed by a conveyor belt into extrusion molding machine, molded into the brick kiln, using coal gangue’s feature of spontaneous combustion which can burn out a piece of red "green bricks". The vigorously develop coal gangue and fly ash utilization provide a very broad way in development of building materials industries, and can promote the good development of its new green building materials industry.

    Based on abrasive properties of coal gangue and fly ash, Hong Cheng vertical mill can grind them into required powder particle size. Hong Cheng vertical mill mainly consist of main frame, feeder, classifier, blower, plumbing fixtures, storage hopper, electronic control systems, collection systems, etc., highly reliability, the use of roller stopper device can avoid severe vibration caused by mill lack of material feeding in work time. For fly ash and coal gangue, the mill uses the new roller sealing device, seal is more reliable seal and without blower sealed, can further reducing the oxygen content of the mill, explosion suppression performance is more excellent.

    HLM vertical milling machine has a large range of grinding, can grind cement raw material, clinker, power plant desulfurization limestone powder, slag powder, manganese ore, gypsum, coal, barite, calcite, bauxite and other materials, therefore, widely used in electric power, metallurgy, cement, chemicals, non-metallic mine industry, can grind high hardness, high moisture, high fineness of non-metallic mineral materials, to achieve new upgrade which Raymond mill cannot further ground, is worthy trusting manufacturer by investors.
