Characteristics of Electrical Automation Control in Powder Production Process

Due to the presence of powder production in different industries, the powder production process is not completely independent. For example, in the large-scale petrochemical industry, powder production is often only the last finished product process of the entire production process. Although the automatic control system used for powder production is relatively independent, it is also a part of the entire factory's distributed control system (DCS).
The design methods, means, and even standards of the automatic control system are consistent with the entire automatic control system of the factory. In some powder application units, such as the magnetic material industry, powder is supplied as a raw material. Many powder materials with different properties undergo a series of processes such as transportation, storage, ingredient mixing, dispersion, grinding, balling, sintering, etc. to produce a new type of powder material. The automation process of powder production in this type of production enterprise is relatively independent, and the standards followed, equipment used, and structural considerations are all carried out and operated in accordance with the agreed standards of the industry. Although there are differences in the industry, the theory of automated production control is the same, and the system composition and automatic control electrical components are mostly the same, with only slight differences or emphasis.
In addition, the advanced level of automation, the size of control structures, and the selection of the same brand of control boxes are also constrained by the scale of powder production enterprises and the production of finished products. This is particularly evident in small and medium-sized powder production enterprises, and the difference in automation level may be significant. However, due to the increasing requirements of the country for energy conservation and emission reduction, relevant policies have gradually been introduced, especially the increasingly strict dust emission standards, which require continuous and automatic operation of the powder production process in a closed environment and strengthen corresponding online detection methods. This has played a significant role in promoting the improvement of the automation level of the powder process.
