Sep 11, 2012 re vibrating screen efficiency calculation. Hello Raj, Screen efficiency is obtained using different equations, depending on whether your product is the oversize or undersize fraction from the screen. The following information is required to calculate the two screen efficiencies;-Qms(f) = Mass flow rate of solid feed.

The material velocity of a circular vibrating screen can be calculated from the corrected theoretical speed of the product formula written below. Example: Determine the material velocity of a screen vibrated at 900 RPM with a 12 mm stroke and 20° degree inclination angle. To calculate the bed depth of the material, the following formula is used.
