The ultrasonic vibrating screen has high screening accuracy and efficiency, and can be used in powder, granule and mucus. It adopts a fully enclosed structure, the powder does not fly, and the mesh is not blocked. It is an ideal screening equipment. Ultrasonic vibrating screen is a derivative product of rotary vibrating screen. It organically combines the ultrasonic controller with the vibrating screen. On the basis of the traditional rotary vibrating screen, a high-frequency and low amplitude ultrasonic vibration wave is superimposed on the screen. The ultra-fine powder receives a huge ultrasonic acceleration, so that the material on the screen surface is always suspended, so as to suppress adhesion, friction, leveling, wedging and other blocking factors, thus solving the problem of strong adsorption, easy agglomeration, high static electricity, high precision, high density, light specific gravity and other screening problems make the screening of ultra-fine powder no longer difficult, especially suitable for users of high-quality and fine powder.
