The vibrating screen consists of a screen body, a vibrator mechanism, a drive assembly and spring suspension units mounted on a frame or support structure.
The screen body is supported by coil springs on which the body can bounce freely. The vibrating motion thus is given by counterweights built on the shaft.
Depending on the location of the shaft, GELEN two bearing inclined screens have two types:
ET-S Series Circular motion screens and ET-SI Series Grizzly screens with center mounted counterweights.
ET-EV Series Elvar screens with off center counterweights which provide different stroke patterns on the deck.
The ET-EL Series Elliptical vibrating screens are of horizontal type screens with triple shaft geared together resulting in elliptical motion. The main advantages of this type of screens are especially when the material is very sticky or flaky they give better results. Also depending on the application, the shape and angle of the ellipse can be adjusted.
