Raymond mill powder coal ash change high quality building ma

 

Fly ash is one of the industrial waste residue of China's current emissions. With the development of the power industry, coal ash emissions from coal-fired power plants are increasing year by year. Therefore, the hazards of fly ash also threaten the sustainable development of the social ecological environment. Recently, it has been learned from the media that the original waste and the much-maligned fly ash has been transformed from garbage to treasure in the comprehensive utilization of the power plant of the megawatt supercritical coal-fired power plant. Not only does it not pollute the surrounding environment, but it also creates good economic value.

It is understood that fly ash is the solid waste produced by coal during combustion. In China, coal ash has become the largest single source of industrial solid waste due to the large number of coal-fired power plants, with annual emissions exceeding 300 million tons. But at present, there are many methods and measures that can be used to reuse fly ash. For example, China huaneng yuhuan power plant has successfully introduced a batch of internationally advanced production equipment, which will make fly ash production quality building materials. Of huaneng yuhuan power plant over the past two years to the comprehensive utilization of fly ash is 1.2068 million tons, equivalent to save 950600 tons of cement, save raw material costs $211 million, save 774400 tons of carbon dioxide into the atmosphere, saving land 301.7 mu, achieved good social and environmental benefits.

Shuguang heavy industry series mill equipment can process fly ash into different particle size powder. In particular, Raymond has a three-dimensional structure, a small area, a complete set of characteristics, fine powder of finished products, and 99 percent of the screening rate, and can be used to process fly ash in building materials. After processed fly ash can be mixed with the right amount of gypsum, and adding a certain amount of coal cinder or water quenching slag aggregates, such as processed, stirring, digestion, grinding wheel, after pressing forming, atmospheric or high pressure steam curing and formed a kind of wall materials; Sintered fly ash bricks are made of coal ash, clay and other industrial waste materials, processed by raw materials, stirred, formed, dried, and baked into bricks. Autoclaved production foam insulation brick of fly ash, fly ash as the main raw material, adding a certain amount of lime and foaming agent, after ingredients, mixing, injection molding and burning autoclaved and become a new type of insulating brick; With fly ash as raw material, appropriate amount of lime, cement, gypsum and aluminum powder is added, and the water is mixed with water, and it is injected into a kind of porous lightweight building materials. A kind of artificial light aggregate which is made by mixing, forming a ball and heating with high temperature.

Shuguang Raymond mill fly ash getting high quality building materials, Raymond mill in performance and quality constantly optimized, the Raymond mill and can be called Raymond mill, its scope of application: Raymond mill is suitable for the barite, calcite, potassium feldspar, talc, marble, limestone, ceramic, glass and other mohs hardness is not greater than magnitude 7, humidity below 6% of inflammable and explosive mining, chemical industry, building materials, metallurgy and other 280 kinds of materials of powder processing, finished product size adjusted within the range 100-325 mesh.
