Ultra-fine powder mill insists on handling fly ash in the end


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. . Welcome to consult and discuss.

Raymond Mill work process


After the bulk material is crushed by the jaw crusher to the required grain size, the raymond mill is used to send the material to the storage hopper, and then the vibrating feeder is evenly and quantitatively fed into the main grinding chamber for grinding, after grinding. The powder is carried away by the fan airflow.
After being graded by the analyzer, the powder with fineness enters the large cyclone collector along with the gas flow through the pipeline, and is separated and collected, and then discharged through the powder tube as finished powder. The air flow is sucked into the blower by the return air pipe at the upper end of the cyclone collector. The entire air flow system of the machine is closed and circulates under positive and negative pressure.
The above is a detailed introduction about the structure and working principle of Raymond Mill. The relevant staff can refer to it. Before the raymond mill is installed, it should be properly kept. A complete maintenance system must be established to prevent the machine from being exposed to the sun, rain or rust. In the process of using Raymond Mill, it requires a fixed number of people to look after it. It also requires the operator to have a certain level of technology, but also to understand in detail its structure and working principle, and familiar with the operating procedures.
