High-frequency vibrating screens - Wikipedia

Its high frequency characteristics differentiates it from a normal vibrating screen. 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.
