The ultrasonic screening system is composed of ultrasonic resonance power supply, oscillator and resonance ring. The high-frequency electric oscillation generated by the ultrasonic resonance power source is converted into the longitudinal oscillation wave in the form of high-frequency sine by the oscillator. These oscillation waves are transmitted to the resonance ring to make the resonance ring generate resonance, and then the vibration is uniformly transmitted to the screen surface by the resonance ring. The materials on the screen are subject to low-frequency three-dimensional vibration and ultrasonic vibration, which can not only prevent the mesh from clogging, but also improve the screening output and quality.
