Overview

Highfrequency vibrating screens Wikipedia

The high frequency vibrating screens usually operates at an inclined angle, traditionally varying between 0 and 25 degrees and can go up to a maximum of 45 degrees Besides, it should operate at a low stroke and has a frequency ranging from 1500 7200 RPM Pretreatment of the feed is often required before the use of the high frequency screen as the apertures in the screen may become blocked
