Aggressive vibration is applied within a range of 3600–5000 RPM directly to the screen media, allowing for higher capacity and more efficient sizing when compared with conventional screens. Under the effect of high-frequency vibration, a smaller bed depth is obtained, which allows for stratification and greater screening efficiency.

If the screen is only operating at 75% efficiency, then 25% of the desired product is going somewhere else. The performance of a screen is affected by four variables: eccentric throw, frequency (rpm), angle of adjustment and throw direction. By manipulating these variables, the operator can dial in the screen to match the application and material.
