Hongcheng vertical mill is advanced equipment of fly ash geopolymer applications field

    Fly ash as solid waste emissions from coal-fired power plant is destructively to environment. Research institutions gradually stepped up research efforts to fly ash after discovered its huge cycle application opportunities. At present, China's comprehensive utilization of fly ash could reach up to 70.07%, utilization in cement, concrete, wall materials and other areas has reached 88%. As the technology for utilization of fly ash continued to increase and expand the field, fly ash has been continuously upgraded, such as fly ash cement and concrete; fly ash geopolymer; Fly-ash waste rock filling materials and technologies; fly ash wall materials; ash artificial lightweight aggregate; fly ash building and sanitary ceramics and refractory ceramics, refractories; plastics and rubber industries filler; separating high fly ash material and valuable elements and extraction; fly ash carbon removal technologies; fly ash in wastewater treatment and exhaust gas treatment; fly ash geopolymer is one of them which has a depth of promising development projects.

    First, what is fly ash geopolymer?

    Geopolymer is a complex mixture of different raw materials; its structure will be different cause of preparation process. Geopolymer is a new type of green materials. Now for green, environmental protection and energy saving, high-performance industry, the advent of the geopolymer attracts worldwide attention.

    With the deepening of the study, geopolymer raw materials have continued to increase, a lot of solid waste can be an ideal raw material, such as blast furnace slag, steel slag, fly ash, coal gangue, glass, all kinds of slag, construction waste, etc. , it may be the ideal geopolymer materials after processing and treatment.

    Second, fly ash geopolymer presentation

    Geopolymer having a high strength, good corrosion resistance and durability, fast hard early strength as well as a wide range of sources of raw materials, low cost, low energy consumption characteristics, the prospects are very broad, therefore, regarded as green materials.

    Geopolymer energy consumption is low, only 30% of cement production and energy consumption, such as the use of active solid waste, energy consumption can be reduced to 10% of energy consumption in cement production. Because of its durability, impermeability and strong, fast hard early strength and other superior performance, it is possible to replace cement in many occasions as building materials, high-strength materials, and sealing materials, exhibit a broad application of prospects.

    Third, select fly ash as raw material advantages

    1. Abundant resources: our country is a big coal country; a lot of coal use will inevitably produce large amounts of fly ash. For now, fly ash emissions by 1.6 million tons; the accumulated amount over one billion tons with the sustained and stable development of China's economy, coal use will continue to increase, and cement manufacturing and other industries will increase the intensity of the use of fly ash.

    2. Effectively alleviate the pressure on the environment: Ash is a tiny particle of dust, discharged waste from coal-fired power plants or other coal-fired devices, easy to different degrees of pollution to atmospheric environment, the human living environment, human, vegetation. Therefore, how to effectively use of fly ash, turning it into useful material, with its production of geological polymeric material is an effective solution to the problem of pollution of fly ash.

    Fourth, vertical mill equipment has become the preferred fly ash

    Vertical mill is an advanced energy efficient grinding equipment, Guilin Hong Cheng produced HLM vertical mill integrate drying, grinding, classification, transport as a whole, suitable for all kinds of material. Grinding broad range of material can be adjusted from 2-5mm to 15um by 97% of the finished product fineness. With high grinding efficiency, low power consumption, big feed size, easy to adjust fineness, process equipment is simple, small footprint, low noise, low dust, easy maintenance, low operating costs, less wear-resistant material consumption, etc., HLM vertical mill break through the traditional Raymond mill grinding high hardness, high moisture material grinding pattern of advanced equipment, and thus become the preferred choice of fly ash powder preparation for many clients.
