Coal ash is the powder that after coal fired boiler burns, forms, bases Si02, Al2O3, Fe3O4, FeO, still have a few CaO, MgO, main use is urban rubbish is filled bury; Coal ash dam is handled; Project of road, railroad, catchment; Irrigation works, channel, bank, dam, brake prevents ooze; Harbour fluid library prevents ooze; Be defeated by flotsam of channel of water, infusion, solid to pile up prevent ooze; Housetop prevents leakage; Garage of storehouse of building basement, underground, underground is moistureproof; Picket film cofferdam, surround the sea to build project of land, dock to wait. Coal ash has adsorption, purify, the action such as catalysis, can replace a lot of medicines and chemical reagents to have all sorts of tests with coal ash in the lab so, can use at lifesaving in daily life, purify foul water, fertilizer and improved and acidity soil can be made in production, processing industrial waste water can be used to wait a moment in environmental protection.

Classics grinder equipment is treated coal ash use is more extensive: 1, can use as if the volume that contain carbon is high the fuel of fluid-bed boiler, burn circularly; 2, model coal modifier, coal ash is in dispersedly model the caking property that hot condition coal can reduce in coal, apparent to the aerification coal effect of low grey melting point; 3, can use at cement production, alkalescent oxide is contained in coal ash, can enhance the water imbibition of cement, enhance cement quality.

Use ash of cement of 525 common silicate, silicon at the same time, super- fine fly ash, efficient the agent that decrease water and standard are arenaceous wait for craft of raw material and conserve of damp and hot, can make up a compressive strength to amount to the active and pulverous concrete of 2 0 0MPa. After the steel fiber that enters certain amount in mix into, the compressive strength close 2 50MPa of active pink concrete, fight fold intensity to achieve 45MPa. Glue of mix into quantity, water compares fine to exceeding fly ash, arenaceous glue is compared and the element such as quantity of steel fiber mix into exceeds concrete of powder of active of fine fly ash to fight at mix into fold, the influence of compressive strength undertook improve and rising.

At present market of whole fly ash is in try a case for be more than, whole Chongqing market is right fly ash year demand is 1.2 million tons. The difference on fly ash quality will cause devoid market competition ability, year after year loses export market, cause grey field keep long in stock finally. National regulation, the fly ash that is used at building concrete must achieve national II grey matter to measure a level. Pass mill, fly ash became commodity, the one level that basically is used at major project is grey, 2 class are grey, 3 class ash got affirmation.

What CLIRIK is versed in what the basis grinds stock again is fineness and those who give makings stock is fineness, produces grinder can divide Ramon grinder, YGMX exceeds fine grinder, grinder of high-pressured middling speed, transcend the genre of several kinds of grinder such as large grinder. Different milling equipment can machine fineness with crop each are not identical, satisfy you to produce the different requirement that exceeds fine fly ash.
