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. The allowable depth of bed should not exceed 5 ...
Screening efficiency can be expressed relative to oversize (Eo), undersize (Eo), or overall (E). The following equations are used to calculate each of these respectively: Eo = [Qms (o) X (1 Mu (o))] / [Qms (f) X (1 Mu (f))] Eu = [Qms (u) X Mu (u)] / [Qms (f) X Mu (f)]
· re vibrating screen efficiency calculation. Dear Raj. Mr Ted is right to find the actual efficiency of any vibrating screen. but if TPH is not known than feed material undersize, product undersize and overproduct undersize % can be used to find the efficiency. I am giving an example below for your understanding. In limestone separation for () 30mm . The Feed material to the screen .
