Terex® Simplicity Four Bearing Inclined Screen

The Terex® Simplicity four-bearing gyrating screen is the original mechanically vibrated screen using a counter-balanced eccentric shaft. The shaft is accurately machined to provide an exact counter-balance for the weight of the entire frame and deck structure, building in a fixed positive stroke that will not dampen under load.  

Terex® Simplicity four-bearing screens can be mounted by supporting the main frame from below, or suspending it by rods or cables attached to the plant superstructure. With either type of mounting, positive action of the screen's counter-balanced shaft will maintain full effectiveness and minimize transfer of vibration to the support structure. Sizes range from 3’ x 6’ to 8’ x 20’ in one, two, and three deck units.
