Trough chain conveyors

Trough chain conveyors are used to dose or transport bulk materials from one process to another. Thanks to their flexible design, they can be adapted to almost every system. With the fully closed design, dry and free-flowing materials can be conveyed safely and environmentally friendly. Compared to other conveyor technologies, a trough chain conveyor requires less power per material volume unit. The compact and versatile drives from NORD DRIVESYSTEMS suit almost every plant layout.

  • Foot, push-on or flange-mounted version
  • Robust UNICASE housing
  • Integrated housing vent
  • Case-hardened high-alloy steel gears, and high-quality bearings and shafts guarantee a long service life and high radial forces
  • Ideal gear unit version, depending on the space available

Belt Conveyors

Belt conveyors are used for higher conveying rates with longer conveyor lines, and for individual discharge. As the material is at full rest on the moving belt, they need less drive power and are suited for horizontal and inclined conveying. To achieve the required belt speed, NORD DRIVESYSTEMS offers 2-stage and 3-stage drives over all power ranges.

  • Hydraulic couplings or frequency inverters for soft start
  • Optional backstop to prevent material backflow
  • Special sealing solutions
  • Shrink disc for easy installation
  • Torque bracket, torque arms

Rotary feeders / feeders / slide valves

Bulk materials can be controlled, measured and dosed using rotary feeders, feeders or slide valves, to ensure the correct material flow for the process. An exact positioning, and constant and freely selectable or variable speeds are relevant to the process and can be achieved with NORD drive technology.

  • Corrosion-resistant versions available for many applications
  • Reversing operation optionally available so that material blockages (e.g. stones) can be resolved.
  • Foot, push-on or flange-mounted version
  • Space-saving design
  • Special sealing solutions

Clearing screws and rotating screws

Discharging remaining materials from a silo is done using silo screw conveyors. Intelligent torque monitoring and the ability for reversing operation allow for overload protection in case of a blockage by foreign materials. Here, NORD DRIVESYSTEMS provides precise and flexible configurable frequency inverters.

  • Robust UNICASE housing
  • Foot, push-on or flange-mounted version
  • Reinforced bearing for high axial and radial load capacities
  • Intelligent drive electronics and torque control

Screw Conveyors

Screw conveyors consist of a conveyor screw supported on both sides, that rotates within a housing and thus conveys the material. The bulk materials can be horizontally, diagonally or vertically conveyed over a specific distance, and exactly dosed, e.g. using sliders. NORD DRIVESYSTEMS offers energy-efficient, easy-assembly and reliable drive solutions.

  • UNICASE housing
  • Special shaft seals for all environmental conditions
  • Easy assembly and disassembly
  • Efficient direct mounting without V-belts and pulleys possible

Bucket Elevators

Bucket elevators are used to transport bulk materials in a vertical direction. With the MAXXDRIVE® industrial gear units, NORD DRIVESYSTEMS offers flexible solutions for torques of up to 282,000 Nm.

  • Optional backstop to prevent material backflow
  • Auxiliary drive available with freewheeling coupling and encoder for maintenance operation
  • Special sealing solutions
  • Hydraulic couplings or frequency inverters for soft start
  • Motor swing base
  • Direct mounting or IEC motor mounting

UNICASE housing

As early as 1981, NORD DRIVESYSTEMS developed the revolutionary UNICASE housing. An enclosed gear unit housing which combines all elements of the gear unit is produced from a single piece of material.

  • A housing block which integrates all bearing points
  • Complete machining in a single step
  • High output torques
  • High axial and radial loads
  • Ultimate reliability
  • Long service life
  • Quiet running

Safe, reliable and efficient drive solutions from a single source


The efficient gear units, motors and frequency inverters from NORD DRIVESYSTEMS contribute to a clean and safe solution. Direct motor mounting via an IEC/NEMA adapter replaces belt drives and exposed, rotating components. The compact design is non-leaking and easy to clean. ATEX-conform drive solutions increase safety against unwanted gas or dust explosions.

  • Safe and application-related drive design
  • No risk of injury due to nip points or freely rotating components
  • Compact block housing without joints that are subject to radial loads or torque


The fully matched components from NORD DRIVESYSTEMS work in perfect harmony, and their reliability makes operation safe and profitable.

  • Large output speed range and flexible attachment options
  • High precision, rigidity and strength due to UNICASE housing
  • Non-leaking operation
