Its high-frequency characteristics differentiate it from a normal vibrating screen. High-frequency vibrating screens usually operate at an inclined angle, traditionally varying between 0° and 25° and can go up to a maximum of 45°. They should operate with a low stroke and have a frequency ranging from 1500 to 9000 RPM.

An efficiency of 99% will equate to a significant loss of capacity. Efficiency is the ratio of undersize material in the feed that actually passes from the media to the undersize material that should pass from the media. This ratio is desired to be , however this is not possible due to the factors affecting the process.
