Eriez Permanent Suspended Magnets

Automatically remove large amounts of ferrous contamination from non-ferrous materials conveyed on almost any type of conveyor or chute


Suspended Permanent Magnets



Eriez Suspended Permanent Magnets

Suspended Magnetic separators have proven to be the most effective for the removal of unwanted iron from heavy burdens of material being conveyed on fast moving belts. They are ideal for separation applications on wet or dry, fine or coarse materials in large or small tonnages. Safe, sure, tramp iron removal protects costly processing machinery and assures the purity of the product.

The uniquely designed magnetic circuit is long and flat, providing a greater area of magnetic coverage with a maximum depth of field and with less head room required than with an electromagnet. Operating advantages are many, possibility of accidental shutdown and shutdown due to power failure is eliminated - strength never varies. The unit operates at peak efficiency at all times - no heat is generated. Elevated temperatures in the 100° to 200°F (38° to 93°C) range have virtually no effect on these separators.

Model CP 20/80L Permanent Magnets

The CP 20/80L are ideal for general tramp iron removal from a range of materials. CP magnets utilize a permanent magnet circuit to provide a continuous and uniform magnetic field across the feed belt to optimize separation efficiency of damaging tramp iron. The self cleaning feature supplied with the unit provides for automatic removal of accumulated tramp metal.

Features and Benefits:

  • Low operating cost
  • No electrical maintenance on magnet
  • No costly shutdowns
  • Uninterrupted magnetic protection
  • Simple installation
  • Powerful magnetic field
  • Permanent magnet requires no power

The magnet is placed across the conveyor belt. A moving continuous belt surrounds the magnet box. Ferrous material is attracted by the magnet and is held on the belt. As the belt moves clear of the magnetic field, ferrous metals fall away into bins for collection and disposal. The CP 20/80L SC–2 is designed for a maximum suspension height of approximately 10 inches (250 mm) on belts less than 36 inches (1 m) wide. Applications involving wider belts or higher suspension may require a larger suspended permanent magnet.

SP Series 6000 Permanent Magnets

MC Models (Manual Cleaning)

Available in 5 strengths, all MC models are cleaned of accumulated tramp iron manually. They are recommended for use where only occasional pieces or small amounts of iron may be in the material flow.

  • Standard mounting hardware consists of adjustable suspension sling.
  • MC models can be easily converted to SC styles giving great flexibility for changing conditions.

SC Models (Self Cleaning)

Available in 5 strengths. SC Models provide completely automatic iron removal and can be installed in an “in line” position or in a “cross belt” position. Each of the two self–cleaning configurations is designed to suit specific conditions and requirements. Space and clearance, conveyor belt speed, burden depth, tramp iron size, etc., are factors that can dictate choice of style.

Both SC models incorporate a short belt conveyor built around the magnet to effect automatic removal of trapped tramp iron from the magnet face.This system features a rubber conveyor belt, bearings, rugged but simple continuous channel frame, adjustable take–ups and shaft–mounted reducer with v–belt coupling to a TEFC motor.

  • Standard mounting hardware consists of turnbuckles.
  • All style SC units are easily demountable from sC conveyor and can be used independently as MC units.
