Application and Development of Ultrasonic Anaerobic Screening Technology in Powder Metallurgy Industry

Ultrasonic anaerobic screening technology is a systematic engineering project. Ultrasonic screening system is an organic combination of ultrasonic system and screening machine. Through the ultrasonic transmission system, ultrasonic energy is transmitted to the screen, disrupting the surface tension of the screen, avoiding the adsorption of ultrafine powder, reducing the probability of screen blockage, and promoting the screening or grading of ultrafine powder or easily adsorbed powder through the screen. The ultrasonic oxygen free screening system, including the ultrasonic screening machine, feeding system, and receiving system, is in a vacuum state, or the entire system is dynamically filled with nitrogen, inert gas, etc., to ensure that the powder completes the screening process without contact with air. At present, many cutting-edge technologies, including aerospace materials, 3D printing materials, electronic materials, and spraying materials, have been applied in multiple fields; Among them, China's first 3D printing high-purity titanium powder anaerobic screening project has provided key screening technology support for breaking the technology research and production embargo imposed by developed countries on high-purity titanium in China, achieving good political and economic benefits.

The technical characteristics of ultrasonic oxygen free screening are: the screening system is oxygen free, ultrasonic high-precision powder separation, and automatic control.
