Mobile star screen

The new XL3 adds to Komptech’s line of large star screens. Its extra long coarse screen deck is a major benefit where coarse screening is a bottleneck, for example with fresh biomass. It brings a definite increase in throughput. The high performance and a semitrailer design for easy transport make the new XL3 perfect for the international market.

The new XL3 offers unmatched flexibility through the simple adjustability of the screen cut and market-leading low energy consumption with all-electric drive, using electricity from on-board generator or grid.

  • Highlights

    Long coarse screen

    If high coarse-grain separation performance is what you need, the extra-large screening surface of the coarse screen deck is a big plus. It improves throughput as well as separation accuracy. Need things really coarse? The new double-screen stars in the coarse screen enable separation in the 100-150 mm range.

  • Highlights

    Always unclogged

    The screen units are continually cleaned by the most simplest and efficient patented CLEANSTAR cleaning system. Each star has a wear-resistant cleaning element that clears the screen gap to the surrounding stars on each rotation. So screening is always in season with Multistar star screens.

  • Highlights

    From fine to coarse

    Particle size can be controlled by varying the rotation speed of the star shafts. The particle size in the bandwidth specified by the star geometry can be changed within seconds by the control panel with touchscreen and visualisation. A screen section from 8-150 mm is covered due to different types and arrangement of the stars.

    Mobility anywhere in the world

    Thanks to its design as a semi-trailer, the XL3 can find a vehicle to tow it almost anywhere. The worldwide use of this system simplifies approvals, and gives the Multistar XL3 unlimited mobility.

Green Efficiency

Green Efficiency

green efficiency® by Komptech is an innovation programme that gives our machines lower consumption and higher performance, and uses the latest exhaust scrubbing technologies. The reward is twofold: Our customers save on operating costs, and the environment - and with it all of us - benefits from reduced CO2 emissions and resource use. 

Innovation in detail
  • Electrical drive of all components (screen deck, conveyors) Advantage: Substantially lower energy consumption and maintenance costs than machines with hydraulic drive
  • Hybrid drive: Energy can be sourced from the grid or generated with the on-board diesel Generator Advantage: Up to 75% lower energy costs when using grid power, up to 25% lower energy costs when running with the diesel generator

Less consumption

15 t

CO2 reduction per year
