Mobile drum screen

The Cribus 5000 opens up a new dimension in drum screening. 50 square meters of screening area along a 7.7 meter long drum, with a hopper holding over 6.5 m³ make it obvious who we developed this high-performance machine for - users who want high throughput with great screening results, especially with small hole sizes. For that, there is no substitute for drum length.

But we did substitute the hydraulic drive - on this model, everything is electric. That minimizes energy, wear, and maintenance costs, and makes the big Cribus one of the most economical machines in its class.

  • Highlights

    Little holes - big performance

    With small hole sizes (< 20 mm) in particular, the length of the drum and its effective screening area become crucial factors. On its way through this 7.7 m drum, all the material is thoroughly screened, with performance that is unique on the market.

  • Highlights

    Hybrid technology

    The power for the drives can come either from grid electric power or the optional built-in diesel generator. The use of grid power reduces energy consumption by up to 75% compared with hydraulic power. On the all-electric version without diesel auxiliary generator, the space saved results in a hopper volume over 8 m³ versus 6.5 m³.

  • Highlights

    Less money per square meter

    At high utilization, operating costs quickly become a major factor. That’s where the Cribus shines - its low-wear friction wheel drum drive, efficient corrugated edge conveyor for the fine fraction, all-electric drive, and much more make the Cribus well-nigh unbeatable on operating costs.

    Ready to go!

    Despite its impressive size, the Cribus is easy to manoeuvre as a semitrailer. Operation and maintenance are also easy and convenient. The operating panel with graphic control, automated startup and electric brush adjustment, plus options like hopper sensor control, remote control, hopper pre-screen and more make this machine exceptionally operator-friendly.

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. 

Innovations in detail
  • Electrical drive of all components (screen drum, 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 25% lower energy costs when running with the diesel generator, up to 75% lower energy costs when using grid power
  • New drum design with enlarged Diameter Advantage: Higher screening performance per m² screen area
  • Wheel Grip-drive System Advantage: Direct drive of screen drum without chain but highest efficiency
  • Drive for hopper belt at drum side Advantage : Lower power needed for material transport, lower wear for conveyor belt
  • Discharge system with counter-travel collection belt and corrugated edge conveyor for fines Advantage: Lower power needed by the system, contributing to lower energy costs
  • Frictionless sealing systems for all discharge belts Advantage: Lower energy need in comparison to rubber contact seals
