BJ Magnets’ Self-cleaning Permanent Overbelt Magnet also known as Overband Magnet or Cross belt Magnet is a type of magnetic separator equipment used to remove ferrous metals and other magnetic related materials from a conveyor belt or other moving material stream. As your ideal equipment for the separation of ferrous contaminated material; it can be suspended on gantries above a conveyor belt installation to extract ferrous content from conveyed loads before they reach further downstream processing.
BJ Magnets’ Self-cleaning Permanent Overbelt Magnets are very reliable and can provide ferrous separation for belt widths up to 2400 mm with working gaps up to 1000 mm. They can also be installed for belt widths up to 900 mm, with working gaps up to 600 mm. Apart Gantries which facilitate easy access for routine maintenance, the BJ Magnets Overbelt Magnetic Separators can be designed and manufactured featuring:
-
-
- Electromagnets and permanent magnets
- “Cross-belt” or “in-line” arrangement
- Manual or self-cleaning.

PRODUCTS
BJ Magnets’ series of Self-cleaning Permanent Overbelt Magnets are made with high-performance NdFeB rare earth, or Ferrite magnets – which consist of permanent magnet core, an unloading iron belt, a reducer motor, a very rigid frame, a driven rollers and other parts, used for variety of conveyors to adsorb ferromagnetic material from non-magnetic materials. With an automatic unloading iron device, the ferromagnetic material is automatically thrown out by unloading iron belt device, so as to achieve the purpose of the automatic unloading iron. Then an automatic belt-driven with self-cleaning mechanism dumps the trappings into collection bins located on the side of the conveyor.
BJ Magnets’ Self-cleaning Permanent Overbelt Magnet can be used to detect and remove metal contaminants in a range of industries including and not limited to:

APPLICABLE REQUIREMENTS
The machine has a wide range of applications with energy saving and easy maintenance, in which case the failure rate is very low, as it is stable and very reliable for operation in extremely harsh environment. The BJ Magnets’ Self-cleaning Permanent Overbelt Magnet is designed to be suspended over the conveyor belt, typically via a pulley system or a frame, with the magnet being positioned such way to create a magnetic field across the width of the conveyor belt.
As the conveyor belt moves, the magnetic field attracts and lifts ferrous metals (e.g., iron, steel) out of the material stream – And the attracted metals are then carried by the magnetic field to the side of the conveyor belt, where they are discharged into a separate collection area. The non-magnetic materials continue however moving along the conveyor belt, in which stance they get separated from the ferrous metals. This mechanism ensures efficient separation of ferrous metals from non-magnetic materials as it not only reduces contamination and improves product purity; but also protects equipment from damage caused by metal debris.
The BJ Magnets’ Self-cleaning Permanent Overbelt Magnet is designed and manufactured with magnetic field strength of up to 10,000 Gauss in the aim of providing to concerned industries with a reliable and effective means of ferrous tramp metal extraction. Both the belt width and the conveyor speed can be customized to best suit your need.
The machine is imbedded with a very powerful plate magnet covered with a vulcanized rubber cleated belt and a shaft mounted unto a helical worm gear motor, which is also available in various voltages for simple hook up installation. The Cross Belt is used in the magnetic separation of ferrous materials from products to ensure a safe, metal free output. These powerful magnets are usually installed above conveyor belts, and draw the unwanted metals upwards and away from the conveyor belt to allow for uncontaminated production. With the self-cleaning ability, the belt removes tramp from magnets surface which minimize the frequency of shutdowns and maintenance sessions.
BJ Magnets’ Self-cleaning Permanent Overbelt Magnets offer exceptional efficiency since they require no energy consumption and as such, will not fail in the case of power fluctuations or shut off. It is typically installed either directly above a conveyor belt line or suspended over the conveyor head pulley at the discharge point.
The BJ Magnets’ Self-cleaning Permanent Overbelt Magnet comes with key components such as Permanent Magnet, Pulley System, Frame, Belt or Chain.
The permanent magnet is positioned over the conveyor belt, to which ferrous metals are attracted and lifted out of the material stream. The attracted metals are then carried to the side of the conveyor belt and discharged; the non-magnetic materials continue moving along the conveyor belt.
As part of benefits, the BJ Magnets’ Self-cleaning Permanent Overbelt Magnet are very efficient in ferrous metal separation which reduces contamination and improves product purity. Moreso, not only other equipment get protected from metal damage, but it also has low maintenance (no electricity required).
And to the bargain, the magnetic field strength can be designed to reach up to 10,000 Gauss, with a belt width of up to 2,5 meters of which the conveyor speed can be adapted up to 5.08 m/s. With the material handling capacity of up to 1000 tph, the temperature can range between -20°C to 200°C.
