Grain Industry

Drive solutions for the grain industry

NORD DRIVESYSTEMS offers holistic solutions for the special requirements of the grain industry. NORD supports your filling, storage and emptying plants, your grain silos and your processes in the processing and production of various grain industry products. With in-depth application know-how and worldwide technical support, NORD offers complete drive solutions from a single source.

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

Safe

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

Reliable

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
Precision-designed gears with minimal wear
Extraordinary robustness, quiet operation and long service life
Options for coupling, cooling and motor swing base
Status monitoring

Efficient

NORD DRIVESYSTEMS supplies a wide range of electric motors that exceed the latest global efficiency regulations and standards. The powerful and robust motors with low heating withstand peak voltages and, with their efficiency, contribute to lower operating costs and lower energy requirements.

Low-inertia motors are designed for inverter operation and meet the latest international energy requirements.
Efficient operation and optimised motor power
Lower operating temperatures
Longer service life and reduced total costs of ownership (TCO)
