Overband Permanent Magnet Separator
Power-free overband separation for light to medium tramp metal
The Overband Permanent Magnet Separator delivers the same suspended, self-cleaning cross-belt separation as an electro overband, using a fixed array of high-energy magnets instead of a powered coil. It is the practical choice where tramp metal loads are light to moderate and a permanent electrical connection to the suspension structure is impractical or costly, such as outdoor stockyards, mobile crushing plants, and remote conveyor runs. Captured tramp metal is carried away and discharged by an internal self-cleaning belt, keeping the main line running without interruption. Because there is no coil, there is no risk of electrical failure interrupting protection, and running costs are limited to routine mechanical maintenance. Latif Engineering sizes the magnet array and suspension height to the specific burden depth and belt speed of each installation.
- No electrical power required for the magnet array
- Self-cleaning internal belt, continuous discharge
- High-energy ferrite or neodymium magnets
- Suitable for outdoor and remote sites
- Custom suspension height and belt length
- Consistent field strength, unaffected by voltage
- Low running cost, minimal maintenance
- Weatherproof housing

Applications
Frequently asked questions
Does the internal belt need power even though the magnet doesn't?
Yes, a small motor drives the self-cleaning discharge belt; only the magnet field itself is power-free.
Is it strong enough for heavy rebar or large tramp metal?
It suits light to moderate tramp loads; for heavy or deeply embedded metal an electro overband is recommended.
Can suspension height be adjusted after installation?
Yes, within the engineered range, to fine-tune capture as burden depth changes.
How often does the magnet array need replacing?
High-energy magnets typically retain effective strength for many years under normal operating temperatures.
