Our country is a big country in producing coal, with coal as base fuel for power production. In recent years, China's energy industry develops steadily, generating capacity of annual growth rate of 7.3%, the rapid development of electric power industry, brings the fly ash emissions increased dramatically, coal-fired power plant emissions of fly ash amount per year has increased year by year,2000 is about 1.5tons, by 2010 will reach3tons, to our country the construction of national economy and ecological environment caused great pressure. As the coal consumption of power, China's fly ash emissions increase rapidly, the invisible brought enormous pressure to the environment. Along with the increasingly serious environmental problems, to improve environment and accelerate the recycling of resources, is one of fly ash resources development use a pressing matter of the moment. The comprehensive utilization of powdered coal ash to the use of advanced technology, reasonable process, reliable equipment, reduce production costs, ensure the quality of products, and in accordance with the corresponding national standards. Fly ash also contains carbon, iron, aluminum and hollow beads and other useful components, the first recovery and extraction of useful components, and then to high volume production of building materials products for the premise, is the elimination of fly ash hazards, make resource of advantageous way. At present, domestic commitment to the milling industry of Shanghai Xia Zhou heavy pound introduced high-pressure grinding machine, grinding fineness of500 mesh can be controlled in the (25 microns ) -2500 mesh (5 microns ). For fly ash cement grinding production, fly ash bricks, fly ash silicate block, fly ash aerated concrete and other building materials; also can be used as an agricultural fertilizer and soil conditioner; recycling of industrial raw materials and environmental materials; fly ash, fly ash as the main raw material, mixed with a small amount of binder and solid fuel, by mixing, into the ball, high temperature firing and made an artificial lightweight aggregate and so on. Hongxing machinery limited company with high efficiency, environmental protection and milling machine, the production of fly ash comprehensive utilization effect of prominent, can alleviate already scarce resources and shortage, and can solve the problem of environmental pollution. Therefore, to improve the comprehensive utilization of powdered coal ash, to our country resource use and pollution prevention aspects have a tremendous role in promoting. With the mill technology development, application development, the comprehensive utilization of powdered coal ash will improve greatly. With its high quality products such as Cement making machine, Artificial sand washer, Feed grizzly, Vibrating screen, Raymond mill, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
