Elliptical motion vibrating screen

Fiebig elliptical motion vibrating screens are driven by two centric mainshafts, which generate a swing diameter as in a free running drive. Another synchronized shaft transforms the swing diameter into an ellipse defined by its task. The second shaft distorts the swing diameter into an ellipse. The big advantage of these machines is that they can work with a very low inclination or with no inclination at all.

 
Both shaft drives are controlled by a frequency converter based on the master-slave-principle. The elliptical motion vibrating screen is freely adjustable from 0 to 90°at the plant visualization or through an external potentiometer. Dropping angle and speedup can thus be altered while the screen is operating.
