Product Details
Where a single magnetic pole isn't enough field strength for the contamination load, the PML Two Pole Suspended Permanent Magnet steps up. Suspended above an open conveyor, it uses a dual-pole magnetic circuit to arrest ferrous objects and fines from grains, feed stuffs, raw and processed products, dry chemicals, salt, ceramics, cement clinker and coal on power-plant conveyors — the same applications as our single pole unit, with a stronger field for heavier or more frequent contamination.
How It's Positioned
The unit is suspended on chains or a frame directly above the conveyor belt, spanning the belt width. The two-pole design creates a stronger, more concentrated magnetic circuit than a single-pole unit, reaching further into the material burden to hold ferrous contamination against the underside of the housing until it's manually cleared.

Width is selected to match your conveyor belt width, and length/speed rating scales with material throughput. The extra 91mm of housing depth over the single pole range (245mm vs. 154mm) reflects the added second pole assembly.
Key Advantages
- Stronger Field Than Single Pole
The dual-pole circuit reaches further into the material burden for heavier contamination loads.
- No Power Required
A fully passive permanent-magnet system suspended above the line.
- Eight Standard Sizes
500mm to 1200mm, matched to common conveyor belt widths.
- Protects Downstream Equipment
Stops tramp iron before it reaches crushers, mills or bagging lines.
Two Pole vs. Single Pole — Which Do I Need?
Two pole suspended magnets deliver a stronger magnetic circuit for heavier or more frequent contamination. For lighter loads, our Single Pole Suspended Permanent Magnet is a lower-cost option.
Frequently Asked Questions
How is it cleaned?
Accumulated tramp iron is removed manually at scheduled intervals — how often depends on your contamination load and line speed.
Why choose two pole over single pole?
The dual-pole design gives a stronger, more concentrated field, useful where contamination is heavier or the burden depth is greater than a single pole magnet can reliably reach.
Can it be sized to a non-standard belt width?
Yes — the standard range covers 500–1200mm belts; custom widths are available on request.
