Airflow sieve is a high-precision screening equipment for meshing fine powders, which is widely used in chemical, pharmaceutical, food, paper, metallurgy, building materials, rubber, machinery and other industries. It can be used for continuous screening of powdery materials with fineness ranging from 80 to 500 mesh. The screen can be replaced at will. Airflow screening machine (airflow sieve) has high screening efficiency, large output, precise fineness and no super-mixing phenomenon. The screen is not loaded and has a long service life. It has a wide range of fineness, fully enclosed structure and no dust spill. Scattered, low noise, low energy consumption, continuous operation and convenient maintenance. First, the working principle of air flow screen The air flow screen realizes the classification of the material by the vibration of the motor of a certain frequency, and the material is classified by the screen. Because of the open screening, the dust of the material screening process is large, and waste and loss are invisible in the material screening process. It also leads to great pollution of the natural environment and working environment. At the same time, vibrating screening has great requirements on materials, such as specific gravity, viscosity, and chemical properties. As a result, many materials with small specific gravity cannot pass through the screen, and many materials required for high mesh screening cannot be screened. Second, the characteristics of the air flow screen The screen is installed vertically, without load, and has a long service life. It is convenient and simple to replace the screen. The structure is closed, negative pressure production, no dust and dust, and does not pollute the environment. The structure is closed, negative pressure production, no dust and dust, and does not pollute the environment. Low noise, low power consumption, suitable for continuous production operations, easy to use and maintain. It has a wide range of fineness, high screening and classification, and can screen 500-800 mesh powder materials. It is very difficult to screen and classify powder materials with 200 mesh or more. The screening efficiency is high, and the permeable rate can reach 85-95%. Third, the application of air flow screen The airflow screen eliminates the traditional principle of gravity potential operation and opens up a new way of sifting the kinetic energy of the carrier fluid. It uses a high-speed airflow as a carrier in a closed state, so that the fully diffused powder particles have a sufficiently large kinetic energy to the screen. Spraying, to achieve the purpose of rapid grading, the flow sifter utilizes the characteristics that the powder particles are small, light, easy to float, and has good fluidity, and fully diffuses into the airflow, and the powder is no longer agglomerated, but sequentially flows with a single particle. Through the screen, the airflow screen has large output, high efficiency, no sticky net, no mesh, and fineness. Widely used in dozens of industries such as chemical, food, building materials and coatings.
