Fly ash is fine ash that is collected from coal-fired flue gas. Fly ash is the main solid waste discharged from coal-fired power plants. The main oxide composition of fly ash in thermal power plants in China is: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 and so on. Fly ash is one of the larger industrial wastes in China. With the development of the power industry, fly ash emissions from coal-fired power plants have increased year by year. A large amount of fly ash without treatment will produce dust and pollute the atmosphere. If discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to the human body and living organisms. In addition, fly ash can be used as a concrete admixture.SBM ultrafine mill insists on handling fly ash in the end. At present, there are many types of mills for fly ash, most commonly used in Raymond Mill, over-pressure mill, and high-pressure suspension mill. Extensive, because fly ash replaced part of the cement, the workability, homogeneity, water exudation, and pumpability of the agitated concrete were improved, which reduced the amount of water used and prolonged the setting time of fresh concrete. It is beneficial to inhibit the alkali aggregate reaction. In particular, it is advantageous to reduce the heat of hydration and delay the rate of heat release so that the large-scale water industry and large-volume concrete are not cracked after pouring. However, these uses must be performed when the fly ash has a certain degree of fineness and meets the required standard, ie, graded ash. In order to solve this problem, Shanghai SBM Machinery Co., Ltd. has specially launched a vertical milling machine. This machine is developed on the basis of the design concept of integrated milling machine and combined with the actual needs of the domestic cement, coal, fly ash and other fields. .
