Product Details
Also known as an overband magnetic separator, the PML Magnetic Cross Belt Separator is a self-cleaning solution for continuously removing ferrous contaminants from material moving on a conveyor belt below it. A powerful overhead-suspended plate magnet is housed in its own inverted mini-conveyor — tramp iron is lifted up and out of your material stream and carried away by the separator's own belt, with nothing to manually clear.
How It Works
Suspended above your main conveyor, the separator's own motor-driven belt runs continuously across the face of the magnet. Tramp iron is pulled up out of the material stream below and held to the separator's belt until it travels clear of the magnetic field, where it drops away on its own — a genuinely self-cleaning suspended magnetic conveyor, not just a static magnet that needs periodic clearing.
Medium or High Intensity
| Grade | Magnet | Strength at Distance | Best For |
| Medium-Intensity | Strontium Ferrite | 450 Gauss | Larger tramp metal from ∼200mm burden depth |
| High-Intensity | NdFeB (Rare Earth) | 700 Gauss | Bolts, nuts, angles and metal pieces from ∼300mm |
Standard Range
| Model No. | Effective Belt Width (mm) | Length (mm) | Motor | Weight (kg) |
| CPM 50 / 50F | 500 | 1722 | 2.2kW | 665–691 |
| CPM 65 / 65F | 650 | 1872 | 2.2kW | 840–936 |
| CPM 80 / 80F | 800 | 2022 | 2.2kW | 1034–1151 |
| CPM 100 / 100F | 1000 | 2222 | 2.2kW | 1370–1541 |
| CPM 120 / 120F | 1200 | 2422 | 2.2kW | 1670–1833 |
"F" suffix models are the ferrite (medium-intensity) build; standard suffix is rare-earth (high-intensity). Power supply is 440V, 3-phase, 50Hz throughout the range.
Construction
The magnetic system is CAD-optimised and stainless-steel encased for maximum flux across the material below. Drive is via a shaft-mounted worm-geared motor with IP54 protection. The separator belt itself is heavy-duty 3-ply rubber, 10.5mm thick with anti-wear rubber on both faces, vulcanised endless and running at 1.5 m/s. Bearings are sealed-for-life pillow blocks, pulleys are crowned-face mild steel with slipper-plate tensioning, and a full-length stainless steel guard protects against nip points and belt damage.
Key Advantages
- Truly Self-Cleaning
The separator's own belt continuously clears captured tramp iron — no manual intervention required.
- Built for 100% Duty Cycle
Rugged construction rated for continuous, uninterrupted operation in harsh industrial settings.
- Deep, Concentrated Field
Reaches into the burden depth to catch tramp metal other separators miss.
- Flexible Mounting
Trolley or cable suspension options, with Plummer block arrangements for simple belt alignment.
Where It's Used
Recycling, mining and minerals, food processing, steel and slag processing, ceramics and powders, wood processing, aggregate and quarrying, packaging, power stations, plastics and glass manufacturing, and pharmaceutical industries.
Frequently Asked Questions
Is this a metal detector?
No — it's a magnetic separator, so it only reacts to magnetic (ferrous) materials, not non-magnetic metals like most stainless steels, aluminium or brass.
Medium or high intensity — which do I need?
Medium-intensity ferrite suits larger tramp metal from a shallower burden depth; high-intensity rare-earth reaches further into the material and catches smaller pieces from greater distances.
How is it mounted?
Trolley or cable suspension options are available, with a welded support frame and eyebolt fittings for your suspension slings.
