Technical notes vibrating screens,4.1 classification based on sieving vibrating screens the basic method of operation of a screen is very simple. the screen presents a barrier to the passage of oversize material while it readily passes undersize material. It is only necessary to ensure that each particle has an opportunity to reach the screen.

linear vibrating screen is driven by double vibrating motors. when the two vibrating motors are rotating synchronously and reversely, the excitation force generated by the eccentric block offsets each other in the direction parallel to the axis of the motor, and overlaps into a resultant force in the direction perpendicular to the axis of the motor, so the motion track of the linear vibrating .
taking into account that vibrating screens usually work at high frequencies, a stress-based approach was used to predict the life of the springs. goodman theory for mean stress correction was used together with the von mises equivalent stress. finally, the highest cycle number in the s-n curve defined infinite life results.
