Unique 3-phase oscillation
Screen crossbeams are fitted on two frames (the external and internal frames respectively) that can be moved together.
Flexible screen panels fitted onto these crossbeams are tightened and loosened alternately via the frame movements. High acceleration forces prevent the screen deck becoming blocked up or sticking. The frame movements are generated by an eccentric drive.
The special motion of both frame systems means that three different oscillatory movements are produced on the external frame:
- Circular movement in the feed area – rapid material break-up, high feed rates, even with challenging materials
- The linear movement in the central area ensures optimal contact between the material and screen mesh resulting in efficient screening!
- Elliptical movement against the direction of conveyance results in improved material destratification and ”near-size“ screening.
