High Frequency Screens
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.
Overview
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. A unique rotary tensioning system provides the quickest screen media changes in the market, up to 50 percent faster than competitive models. Our high frequency screens offer ideal gradation control for reclaiming fines in both wet and dry applications.
