High frequency screen walls

High frequency screen walls

Astec high frequency screens utilize high-speed vibration, from 3600 - 4200 RPM, directly induced to the screen media, allowing for increased stratification and material separation. The directly-induced vibration improves screen efficiency at high production rates compared to conventional screens
