Which mill applied to powder gray brick processing is appropriate?

The main source of fly ash is the thermal power plant and city concentrated hot boiler with pulverized coal, of which 90% is wet gray, the activity is relatively low, and the water charge is electricity, polluting the environment, also Not conducive to comprehensive utilization. In order to better protect the environment and facilitate the comprehensive utilization of fly ash, taking into account the maturity of dust removal and dry ash delivery technology, dried ash collection has become the development trend of fly ash collection in the future.

Processing fly ash is more commonly used as a superfine pulverizer, which can efficiently utilize the characteristics of fly ash itself, and ultrafine pulverizer during processing Has good sealing, zero dust emissions in the processing process, reduce dust pollution.

Fly ash is one of the largest industrial waste residers in China, with the development of the electricity industry, coal power plants The flyer emissions increase year by year. A large amount of fly ash will result in dust, pollute the atmosphere; if the drainage is discharged into the water, it will cause the river and the toxic chemicals will also harm the human body and organisms. Further, fly ash can be used as a blend of concrete.

Fly ash is mainly used to produce powder coal cement, fly ash brick, fly ash silicate block, fly ash gas concrete and other building materials, It can be used as agricultural fertilizers and soil improvements, recover industrial raw materials and environmental materials. Modern concrete new technology for high-quality fly ash and efficacy high suction agent composite technology is rapidly developed in the country; high quality fly ash is particularly suitable for formulate pumping concrete, large volume concrete, anti-seepage concrete, anti-sulfuric acid Salt concrete and anti-soft water erosion concrete and underground, underwater engineering concrete, plasma concrete and rolling concrete. The fly ash concrete has the advantages of good volatility, strong pumpability, improved termination, improved impact capacity, and increased antifreeze.

During the concrete, a large amount of cement and fine aggregate are saved; reduce the amount of water; improve the sum of concrete mixes; enhance the pump of concrete Sex; reduce the creep of concrete; reduce hydration heat, thermal energy expansion; improve concrete impermeability; increase concrete land modification.

First, before introducing the process and the mill type, first introduce the specific use of powder coal ash:

1. Make concrete raw materials: fly ash can be used as concrete raw materials, and the use of fly ash can enhance concrete strength in concrete and improve the quality of concrete.
2, used as chemical raw materials: fly ash can be made into polymer filler, for chemical field, and high-purity alum can also be extracted to synthesize alumina.
3, processing compound fertilizers: fly ash contained rich silicon, boron, sulfur, calcium, etc., can improve soil structure.
 4, brick: fly ash can also be used to make hollow bricks, which is relatively wide in architectural fields.

Second. What is the craft process of fly ash?

The granularity of the fly ash is already very fine, no need to be broken, and can directly enter the grinding machine. The flyer can be grounded into a powder of different granularity required by the mill, and then used in different industries.
