The Advantages And Application of Ultrasonic Vibrating Screen

Since some ordinary vibrating screen equipment can only screen particles below 200 mesh, and for 200-600 mesh material particles, it is necessary to use a vibrating screen with a higher vibration frequency for screening, so the ultrasonic transducer can be used from 20KHZ. Raised to 60KHZ, it has a good screening effect for some tiny particles.
