Flip-flop screen TRISOMAT

for difficult to handle material

The flip-flop screen TRISOMAT is perfectly suited for difficult to handle material. These screens perform outstandingly where the decks of conventional screens clog or stick. 


  • high specific feed rate
  • unique 3-phase oscillation
  • minimized clogging and sticking
  • minimized dynamic loads
  • maximized reliability
  • mechanically strained screen mats
  • feed material is accelerated to 50 g at the maximum

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.

Trisomat screen decks make everything possible

High acceleration being generated by stretching of the screen mats and over expansion of the openings result in almost clog-free screening. Our specialists will assist you to select the optimal screen material and the fixture best suitable for the feed material.
The screen decks can be bolted or keyed alternatively. Screen mats can be raised for small cutpoints to provide a side sealing.
