Through finely ground, fly ash becomes a commodity, the main focus of the project for a gray, two gray, three gray and so was confirmed. Vico Heavy materials according to the fineness of grinding and discharging materials fineness, the production of mill can be divided into Raymond Mill, YGMX super thin mill, high-speed grinding mill, large milling machine and a few other mill types. Different milling equipment can process the fineness and yield different, producing ultra-fine fly ash to meet your different needs.

Coal-fired boilers burning coal ash is formed after the powder, the main component of Si02, Al2O3, Fe3O4, FeO, a small amount of CaO, MgO, etc., mainly used for municipal solid waste landfill; ash dam treatment; roads, railways, drainage works ; water, tunnels, dikes, dams, gates seepage; build libraries liquid impermeable; water, fluid channels, the solid waste pile seepage; roof leak; basement of the building, underground storage, underground garage moisture; pile cofferdam film , land reclamation from the sea, pier, etc. Ash adsorption, purification, catalytic effect, so can use coal ash in the laboratory instead of many drugs for various experiments can be used in everyday life saving, clean water, can be used for the production of fertilizer and improved acid soil, in environmental protection can be used to treat industrial waste water and so on.marble grinding mill: http://www.china-hxjq.com/n300.html

Processed by the grinding mill, ash versatile:

1, if high carbon content of fuels can be used as a fluidized bed boiler, the combustion cycle;

2, coal modifier, dispersed in the coal ash can reduce the adhesion of thermal coal, gasification of coal with low ash melting point of the effect is obvious;

3, can be used for cement production, coal ash contains alkaline oxides, can enhance the absorption of cement, reinforced cement quality.

While using 525 ordinary Portland cement, silica fume, ultra-fine fly ash, superplasticizer and raw materials such as sand and standard heat curing process, can be prepared up to 2 0 0MPa a compressive strength of reactive powder concrete in mixed After a certain amount of steel fibers, the compressive strength of reactive powder concrete nearly 2 50MPa, flexural strength of 45MPa. ultrafine fly ash, water-cement ratio, sand-cement ratio and the steel fiber content and other factors in the ultra-doped fine fly ash reactive powder concrete flexural, compressive strength has been improved and enhanced.

The current oversupply situation in the fly ash market, the Chongqing market demand for fly ash was 120 million tons. The gap between the quality of fly ash will result in a lack of market competitiveness, loss of export market year after year, eventually leading to the ash yard backlog. State regulations, fly ash concrete used in construction must meet the national quality standard gray II.
