SUSPENDED ELECTRO c> Suspended Electro Magnetic Separators (SE Magnets) are typically installed above conveyor belts to remove large pieces of tramp metal that represent a hazard to downstream equipment such as crushers, mills, pulverisers and grinders; or to remove sharp metal that can damage or tear expensive conveyor belts, especially at transfer points. APPLICATIONS • Automatic removal of small or large volumes of tramp iron from wide range of feed materials • Special designs for explosion proof applications (compliant with European Atex regulations) • Special design units for apron feeder...

SPECIAL OPTIONS • High flash point coolants • Dust covers • Full guarding / covers • Permanent extension magnets to ensure ferrous is not discharged prematurely • Monitoring devices (over temperature alert, belt rotation and belt misalignment switches) • Atex certified units available Suspended Electro Magnet with full guarding MAGNET STYLES MANUAL CLEAN (MC) Manual Clean (MC) models are periodically de-energised in order to discharge iron accumulated on the face of the magnet. They are suitable for applications where the quantity of tramp iron in the product is low. These magnets are usually...

SUSPENDED ELECTRO IN-LINE POSITION • Magnet suspended over the trajectory of material as it is discharged from the belt conveyor. • This is the preferred option as it is the most efficient use of the magnetic separator i.e. when the burden is ‘opened up’ in flight and is moving directly toward the magnet face. The iron’s momentum towards the magnet can assist in its separation. • When the magnet is in this position, it is essential that the conveyor head pulley is made of a nonmagnetic material.

CROSS-BELT POSITION • Magnet located over the moving bed of material and at right angles to the conveyor. • This position requires a stronger magnet and is not recommended for excessive belt speeds or deep material burdens where the removal of smaller tramp iron is necessary.

SUSPENDED ELECTRO FACTORS INFLUENCING SEPARATION PERFORMANCE • Belt speed: As the belt speed increases, it becomes more difficult to remove ferrous components. Larger, stronger SE magnets may be required for faster belt speeds. • Burden depth: As the burden depth on the conveyor belt increases, a stronger magnetic field is needed to pull the tramp iron up through the material bed. • Size of ferrous component: Small pieces of tramp metal may be extremely difficult to remove especially when they are covered by a heavy overburden of material, compared to large items like bucket teeth, rail spikes...

LARGE FORCE COOLED (LFC) SUSPENDED ELECTRO MAGNETS Eriez’ large force cooled suspended electro magnets are custom-built high performance electro magnets. They can be supplied in either manual clean or self clean arrangements. • Custom designed for wide conveyor belts and feeders • Provide cross-belt coverage on wider than average conveyor belts • Generate a powerful magnetic field capable of penetrating deep burdens on fast moving conveyors commonly found in today’s most productive mines • Force cooled to achieve maximum separation performance and efficiency with given magnet box size • Typically...
