Principle:

The ultrasonic screening system is composed of ultrasonic resonance power supply, oscillator and resonance ring. The high-frequency electric oscillation of ultrasonic resonance power supply is converted into high-frequency sinusoidal longitudinal oscillation wave by the oscillator. These oscillation waves are transmitted to the resonance ring to make the resonance ring resonate, and then the vibration is uniformly transmitted to the screen surface by the resonance ring. When the material on the screen is subject to low-frequency three-dimensional vibration and superimposed with ultrasonic vibration, it can not only prevent mesh clogging, but also greatly increase the screening output value and quality.
