The ultrasonic round screener is installed a ultrasonic generator device on the sieve mesh which makes superfine powder receive the giant ultrasonic acceleration to make the material on the mesh keep state of suspension and restrain the adhesion, friction ,wedging etc and improve sieving and cleaning efficiency.

The ultrasonic generator can improve flat drop in the gravity settling (light touch between powder and mesh), slipping effect and the occluding and wedging of high-density metal on the mesh, solve the adhesion, easy aggregation, high electrostatic, fine, high density and light specific gravity screening problem to improve the sieving efficiency and quality. Show by the sieving through rate , it generally is able to increase the through rate of 50%-400% than one which is not a ultrasonic round screener.
