Introduction: The screening system consists of an ultrasonic electric box, a transducer and a screen. The chassis and transducer generate vibrations and guide the vibrations to resonance. The ultrasonic wave is evenly propagated through the resonator to reach the entire screen surface, and the ultrasonic wave causes the installed screen to start vibrating. This prevents particles from adhering to the screen and improves separation accuracy. More particles pass through the screen object, and the processing time can be shortened.
