The fly ash, discharged by coal-fired power plant, can pollute soil, water and air badly, which is also harmful to people’s health. It not only occupies a great deal of land, but also heavily pollutes local environment.
Dajia Engineering fly ash recycling plant will convert waste fly ash into a kind of hard and honeycombing artificial lightweight aggregate, a product which can be used to economically replace mined stone in concrete, as well as other uses. Fly ash recycling plant uses approximately 95% fly ash mixed in some cases with water and in some cases a small volume of additives. After agglomeration and pelletizing, the green pellets are sintered, creating an aggregate whose characteristics are superior to natural aggregates.
1. Fly Ash Production Process:
Taking fly ash (dry-discharged fly-ash or wet-discharged fly-ash) as main raw material (mixing amount always over 95%), through measurement, mix and agitation, prilling, balling and over 1100°C calcination process, fly ash recycling plant can produce light, high strength and multiple functional new materials.
2. Features
■ With PLC process control, real-time monitor and English menu display, operators can not only control continuously but also perform individual operations. It only needs 3 to 5 workers for the whole line normal production with low labor intensity.
■ Large scale: large-scale automated production with 60,000m3, 100,000m3, 200,000m3 and 300,000m3 production line to choose. We can also design and produce specific scale production line according to customers’ requirements.
■ Large quantity recycling of fly ash: With the unique nucleation technology of fly ash, without adding other additive, the blending amount of fly ash is up to 95%~100%.
■ High yield: over 95% yield.
■ Environmental protection: Using negative pressure induced air for concentrated dust collecting. The concentration of flue gas and dust discharged from the chimney outlet of dust catcher meets national standard.
■ Low energy consumption: static sintering, good sealing, low air leakage rate, over 50% energy conservation.
