Industrial electromagnetic overband magnet (OV)

In brief

• The industrial electromagnetic overband magnet (OV) is a separator installed above a conveyor or in-line at the discharge point, which automatically extracts ferrous items from a material flow.
• It is used in recycling, mining, construction and cement, food processing and the wood industry.
• Its drive is guaranteed for 2 years and it operates 24/7; it can be mounted cross-belt or in-line.

Applications

Electromagnetic overband magnet (OV): a reliable solution for separating ferrous metals:

The electromagnetic overband magnet is an overband magnetic separator designed for the automatic extraction of ferrous items present in a material flow. The electromagnetic overband magnet is used in many applications:

• Recycling and waste management: separation of ferromagnetic materials from mixed materials (wood, plastics, industrial waste).

• Mining industry and mining operations: extraction of ferromagnetic metals from ores.

• Construction and cement industry: protection of installations against metal items present in construction materials.

• Food processing and wood industry: securing processing lines and improving the quality of finished products.

These sectors require high performance, continuous reliability and precise magnetic separation.

Operating principles

Operating principle of our electromagnetic overband magnets:

The electromagnetic overband magnet operates by means of an electrically powered electromagnet that generates a magnetic field:

• The overband magnet is installed above a conveyor or at the end of the belt.
• Ferrous metal items are attracted by the field and extracted from the material flow.
• An integrated belt automatically discharges the metal contaminants to a collection area.
• The system operates continuously, ensuring self-cleaning separation and uninterrupted operation.

Available for cross-belt or in-line mounting, the overband magnet adapts to all configurations.

Operating recommendations

Recommendations from our Lenoir-Mec experts:

To maximise the performance of your electromagnetic overband magnet, our experts recommend:

• Suitable installation height: adjusted according to the size and burden depth of the materials and the distance (mm) to the conveyor.

• In-line installation for flows with strong material trajectory, and cross-belt installation for standard conveyors

• Periodic cleaning: removal of metal build-up to maintain consistent extraction.

• Regular inspection: monitoring of the belt, motor and rollers.

• Integration of an additional protection system (metal detector) to protect industrial equipment

This information helps optimise the service life and protection of your equipment.

Frequently asked questions

What is the OV electromagnetic overband magnet used for?

The OV automatically extracts ferrous items from a material flow. It is used in recycling, mining, construction and cement, food processing and the wood industry.

How does the OV overband magnet work?

An electrically powered electromagnet generates the magnetic field that attracts ferrous items. An integrated belt automatically and continuously discharges them to a collection area.

Which mounting should I choose for the OV?

The OV is available for cross-belt or in-line mounting. In-line installation is recommended for flows with strong material trajectory, and cross-belt installation for standard conveyors.

What are the characteristics of the OV?

It offers a drive guaranteed for 2 years, 24/7 uninterrupted operation and a hollow-shaft geared motor with torque arm. Its double-drilled mounting lugs simplify installation.

How should the OV overband magnet be maintained?

Periodically remove metal build-up to maintain consistent extraction. Regularly inspect the belt, motor and rollers.
