Mobile drum screen

The Nemus is a class unto itself. Like no other, the Nemus combines the practice-proven virtues of its predecessors with new solutions for more convenience and performance. The large steep-walled hopper, and the screen drum with its improved material feed and high-performance discharge system, harmonize perfectly with the proven, robust diesel-hydraulic drive.

The control with visualization makes operation easier, and the longer discharge conveyors up to 3.5 metres boost flexibility in use. Practical details like the easy-cleaning two-stage radiator induction screen, larger material intake support wheels and the extremely good access to all maintenance points reflect close attention to customer feedback.

    Nemus 620: The drum alternative

    For everyone who always wanted to enjoy the benefits of a Komptech screen, but are already invested in existing drum screens, there is a solution: The drum mounting and drive of the Nemus 620 are designed specifically for drums from the competitor SM 620 model.

  • Highlights

    Built tough

    The reinforced chassis, wider tires and stiff frame with high ground clearance easily handle difficult terrain. The sturdy hopper can hold over 5 m³. Like on the Cribus, the hopper belt drive is on the drum intake side so there is no belt slippage, even under heavy loading. Material feed continues without a hitch.

  • Highlights

    More throughput by a good margin

    Within the drum itself, the improved material flow gives up to 10% more throughput. The greater clearance between drum and sidewall allows a wide range of materials and trouble-free screening at larger hole sizes.

  • Highlights

    Clean discharge

    The fine particles are discharged by a cross belt and a profiled discharge belt or by a one-piece corrugated edge belt. The one-piece design prevents material trickle at transfer points, while also giving high capacity and low wear. All discharge belts offer a discharge height of 3.55 m.

  • Highlights

    Maintenance made easy

    Numerous details reduce maintenance effort, time and expense, like the simplified diesel engine radiator cleaning, easier hopper belt replacement, the fines collection belt that comes out as a one-piece cartridge, and the elimination of rubber wear elements on the discharge belts.

  • Highlights

    Mobility the way you want it

    The Nemus 2700 is now available in semitrailer configuration. The higher loading on the rear axle of the truck makes for better handling, and the shorter machine length makes shunting easier. For difficult ground: The Nemus with a tracked chassis.
