Distinguish Ultrasonic Vibration Sieve From Ordinary Rotary Vibrating Screen

Ultrasonic vibration sieve is equipped with a ultrasonic generator that can prevent blockage. Specially, it is suitable for screening light specific gravity materials or fine powder. Generally, ultrasonic screening system consists of oscillator, ultrasonic resonant power supply and resonance ring. The high-frequency vibration which is generated by ultrasonic resonant power supply will change into high-frequency longitudinal oscillation wave through oscillator. This vibration will be spread to resonance ring to make it sympathetic vibration, and then this kind of vibration will be transmitted to the screen mesh evenly through the resonance ring.

Ultrasonic vibrating screen can separate all kinds of powder, enen though the powder is hard screened. In general, ordinary rotary vibrating screen cannot do this. Ultra-fine powder will be effected by large ultrasonic acceleration through mechanical wave which is attached on screen mesh. Generally speaking, compared with ordinary rotary vibrating screen, the passing rate generated by ultrasonic vibrating screen will be increased by 50%-400%. Mainly performances are as follows:

1. Reduce time of cleaning mesh.
2. Doesn’t pollute to powder which is generated by bouncing ball and other auxiliary materials.
3. Reduce screening frequency, keep high precision screening.
