Suspended permanentmagnetic separators oroverband magnets arepositioned over movingconveyor belts or in a chute for the purpose ofremoving ferrouscontaminants from bulk product flows.
Suspended Permanent MagnetsModels CP, OP and TP
Magnet Strength
Eriez offers three permanent magnetic field configurations, CP, OP and TP, providing different field strengths and field profiles. Our highly trained Application Engineering staff will recommend the best model for each specific model.
CP ~ ideal for mobile crushersand steel can separation.
OP ~ suitable for separatingsmaller tramp metal.
TP ~ designed for applicationssuch as removing nailsfrom conveyed shreddedwood.
Eriez also offers an extensiverange of SuspendedElectromagnetic Separators (ref SB 320).
Magnet SelectionThe model of magnetic separatorto be selected is dependent uponthe specific application. EriezEngineers would need thefollowing information todetermine the optimal size andconfiguration for a particularrequirement:
l Material type
l Material bulk density
l Material condition
l Material size
l Type and minimum size oftramp iron
l Maximum lump size
l Conveyor belt/chute width
l Conveyor belt speed
l Conveyor belt/chutedimensions and incline
l Angle of ‘troughing’ idlers
l Machinery to be protected
l Head pulley diameter
l Head pulley material
ApplicationsQuarry industry
Recycling industry
Any other industry where dryferrous contamination is foundon a conveyor belt or chutesystem

Magnet InstallationPosition 1 -Over head pulleyTo achieve maximum separation efficiency, asuspended magnet should be placed immediatelyabove the trajectory of material leaving the beltconveyor as shown.
Position 2 -Across Conveyor BeltThe magnet can also be placed across theconveyor belt. This position normally requires astronger magnet, as separation of metal out of astatic burden is more difficult. Raised, or rappingidlers under the conveyor belt can assist in freeingtrapped iron.

Magnet CleaningExtracted ferrous metals must be removed fromthe magnet face - the unit’s separation efficiencywould otherwise be impaired by an accumulationof metals on the magnet face. There are twoavailable options for cleaning the magnet.
Manual Cleaning (MC)For low levels of ferrous contamination, themagnet can be manually cleaned by wiping themagnet face. This can be easily done with astripper plate (optional extra)
Self Cleaning (SC)A moving continuous belt surrounds the magnetbox. Ferrous material attracted by the magnet isheld on the belt, as the belt moves clear of themagnetic field, ferrous materials fall away undergravity into bins for collection and disposal.
Optional ExtrasFlame-proof motors, special belts, speed sensitiveswitches, belt tracking devices and extensionmagnets are all available as options to suit specificrequirements.
