Suspension Magnet Manufacturer for Industrial Material Handling

A suspension magnet (also called a suspended magnet or suspended plate magnet) is a magnetic separator mounted above a free-flowing product stream—typically a conveyor belt or chute—so ferrous tramp metal is captured from the material flow without interrupting production. Suspension magnets are available as permanent and electromagnetic designs, and they are built to tolerate continuous duty in heavy industrial environments. Their core purpose is to protect downstream equipment (crushers, grinders, mills, pumps), improve product purity, and reduce damage and downtime caused by iron contamination.

Historically, suspension magnets evolved as industries moved from batch processing to continuous conveyor-fed systems. As conveyors became ubiquitous in mining, cement, recycling and food processing, the suspended magnet became a simple, effective way to intercept tramp iron at a point where it could be readily removed. More recently, advances in magnet materials (rare-earth grades), coil design and structural engineering have improved holding power, serviceability and export suitability. A notable market trend is the push toward localising magnet production (including rare-earth-based magnets), driven by supply-chain pressures and incentives for domestic manufacturing.

Core functions and purpose

• Ferrous removal: Traps ferrous particles, scale, bolts, and other tramp iron from conveyed bulk solids.
• Equipment protection: Prevents costly damage to crushers, pulverisers, and downstream sorting equipment.
• Product quality: Improves finished-product purity for industries that require metal-free output (e.g., food, chemicals).
• Safety & compliance: Reduces safety risks and helps meet industry hygiene or product-standard requirements.

Product types & specifications

By magnetic technology

• Permanent suspension magnets: use rare-earth (NdFeB) or ceramic (ferrite) permanent magnets. They need no power supply, are low-maintenance and suited for continuous operation.
• Electromagnetic (electro) suspension magnets: use a coil and power supply; field strength can be controlled, and they are often used where a stronger or adjustable field is required.

By design/mounting

• Plate-type suspended magnets: flat plates suspended above conveyors; common for light-to-medium duty.
• Rectangular / box-type magnets: deeper pole pieces for heavier tramp iron and wide conveyors.
• Oil-cooled electromagnetic plates: for very heavy-duty continuous use where heat buildup would otherwise be an issue.

By capacity/size

• Rated by Gauss/Tesla field strength, pole gap, and working clearance above the conveyor, plus physical width (to match belt widths). Common belt-width matches range from small (300–600 mm) to large industrial (1,200–2,400 mm+). Manufacturers offer custom pole configurations and multiple pole rows for higher capture rates.

Variants available

• Single-row permanent suspension magnets (economical)
• Multiple-pole permanent magnets (higher holding power)
• Electro-suspension with adjustable current for peak capture
• Automated, tilting or lift-off frames for easier cleaning and maintenance

Applications & use cases

• Mining & mineral processing: early-stage removal of tramp iron from ore conveyors to protect crushers and grinders.
  
• Cement & aggregates: removal of rebar, nails and other steel to prevent mill damage.
  
• Recycling & waste processing: separation of ferrous from non-ferrous streams; protecting shredders and sorting equipment.
  
• Food & FMCG: hygiene-critical screening of ingredients on belt lines (permanent designs with food-grade finishes).
  
• Plastics & rubber: removing broken tools, bolts or metal shards before extrusion or moulding.
  
• Power & biomass: protecting feed systems and turbines from ferrous debris.

Benefits & efficiencies

• Minimal process interruption (non-contact suspended capture)
• Lower maintenance and replacement costs vs. damaged downstream equipment
• Improved product quality and reduced customer complaints
• Energy savings (permanent magnets use no power) or operational control (electromagnets provide adjustable capture)
