Mobile drum screen

With the largest screening surface for its overall length, the Cribus 2800 sets the standard in the compact class. Its large-diameter drum improves screening performance, and generous spacing between drum and side walls ensures trouble-free screening even for coarse sizes. This opens up a wide range of applications, where the Cribus shines thanks to its easy operation and high economy.

One reason is the future-oriented drive system: Everything on the Cribus is driven electrically, from the hopper to the discharge belts.

  • Highlights

    Higher performance


    Despite being only 10.6 meters long, the Cribus 2800 boasts a screening area of 28m², the largest in its class. It’s made possible by the large 2.2 meter drum diameter. This makes material clumping between hopper and drum a thing of the past, so that the Cribus has a higher specific throughput than competitors.

  • Highlights

    Save costs!


    Professional users often operate their machines for more than 1000 hours. This quickly makes operating costs a major factor. Its low-wear friction wheel drum drive, an efficient corrugated edge discharge conveyor for fines, electric drive of all components and much more make the Cribus very nearly unbeatable in operating costs.

  • Highlights

    Drum change in 5 minutes


    Just fold down the sidewall, and the drum is freely accessible. To change the drum, the operator needs only run the hopper out of the drum, press a button to raise the drum, and then remove it with a fork loader or hoist. Pros can do it in just a few minutes.

  • Highlights

    Mobility the way you want it


    The Cribus 2800 is now available in semitrailer configuration. The axle at the rear puts more weight on the rear axle of the truck, making for stabler handling.

Green Efficiency

Green Efficiency
LESS FUEL,
MORE POWER

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
