With MULTISTAR ONE GÜNTHER has developed a powerful two-fraction star screen with recirculation of oversizes. The machine is most suitable for the screening of

  • pre-shredded waste wood
  • wood residues
  • roots
  • shredded greenery
  • other screenable materials.



The MULTISTAR technology is exclusively available from our sales partner KOMPTECH

With the new MULTISTAR ONE the treatment of waste wood and biomass is executed with highest efficiency. An upstream shredder, the Crambo from Komptech, feeds the ONE with shredded material. The function of the new star screen is the separation of a defined utilization fraction with simultaneous recirculation of oversizes to the shredder. Equipped with a loading hopper for exact material transfer to the amply dimensioned screen deck, a discharge belt with a discharging height of 4 meters and a recirculation belt with a swinging radius of 220°, the MULTISTAR ONE is able to operate with a throughput capacity of 200 m³/h.

The installation on a hook lift frame ensures compact dimensions, the design of the conveyor belts enables flexibility in installation and the low wear screen deck combined with the electric drive guarantees highest efficiency.

Operating principle

  • Material is fed via the discharge conveyor of the upstream shredder, alternatively by wheel loader or excavator with gripper.
  • The dosing hopper ensures exact material transfer to the screen deck.
  • The undersized grain discharge conveyor, which is designed as a buckled belt, discharges the fine fraction as a defined utilization fraction.
  • At the end of the screen deck all oversizes are discharged through a funnel-shaped chute on to the recirculation belt. This can be swivelled by 220°. The discharge height of up to 4 m enables direct transfer into the shredder.
  • With hydraulic supports, the discharge height for the utilization fraction can be raised by 450 mm. The supports can be controlled individually.
  • The complete electric control takes place via a central control cabinet 760 x 760 x 300 mm (protection type IP56). The plant is manually controlled via potentiometer and simple “Logo Control”.
  • The discharge conveyors are electro-hydraulically folded and unfolded by means of a hand lever.
  • There is unrestricted access to all maintenance positions.
