Ultrafine Mill Used for Fly Ash Grinding

Fly ash is the main solid waste in coal-fired industrial production at present. It is the waste collected from flue gas from coal-fired. In China's coal-fired industry, the main chemical composition of fly ash is sulfur dioxide, alumina, ferrous oxide and other substances. Because there are many domestic coal-fired industries and most of them are large enterprises, the domestic fly ash emission is relatively large, and it is one of the industries that emit more industrial waste residue in China.

If the fly ash is not treated, it will accumulate in the air, which will cause dust pollution and air pollution. Even if it flows into rivers and lakes with the water, it will cause water pollution. Therefore, facing a large number of domestic fly ash discharged waste, we need to take some measures to control it in order to prevent it from causing environmental pollution. Serious harm.

At present, the main industrial process used to control the pollution of fly ash is the grinding of fly ash. At present, in the series of grinders developed by the company, the main equipment used for the production of fly ash grinding is the superfine grinder, which can be used for the grinding production of other materials besides fly ash. These materials are feldspar, calcite, talc, barite, rare earth, marble, ceramics, bauxite, slag, water slag, activated carbon, dolomite, clay, bentonite, gypsum, graphite and so on. In the grinding of the above materials, the ultra-fine grinding machine can grind the massive materials into very fine size and large size. About 200 mesh to 400 mesh. Fly ash can be used in some industrial fields after it is milled and produced by this equipment.

Up to now, the main industrial application of fly ash is in the field of construction. Fly ash after grinding by ultra-fine mill is mixed into concrete to replace a part of fine aggregate and cement. This not only saves the investment of cement and fine aggregate, but also uses fly ash, which makes fly ash play a very important role. Large industrial applications. The main reason why fly ash can be used in concrete production is that it can not only save other materials, but also improve the performance of concrete, enhance the pumpability of concrete and reduce the creep of concrete, which not only guarantees the quality of buildings, but also brings good fortune to the industry of industrial waste residue treatment. Yin, this action is very popular.
