Suspension magnets are specifically designed for the extraction of occasional tramp iron from a product stream being conveyed by a conveyor belt or vibratory feeder.
The magnet is suspended above a conveyor with sling chains setting the magnet face at the correct angle for optimum extraction.
Master Magnets have increased their range of Suspension Magnets over the years to cater for the ever-increasing size of conveyors, deeper troughing and conveyor speeds. Master Magnets can offer customers two types of suspension magnet, depending on specific applicational details. The units are available as either electro or permanent magnets.
Suspension magnets are specifically designed for the extraction of occasional tramp iron from a product stream being conveyed by a conveyor belt or vibratory feeder. The magnet is suspended above a conveyor with sling chains setting the magnet face at the correct angle for optimum extraction. An electro suspension magnet can be repositioned away from the conveyor and de-energised for cleaning. A Permanent Suspension Magnet can be suspended from a travelling trolley so that it can be moved away from the conveyor to be manually cleaned.
Suspension magnets can be used in a wide variety of applications for the removal of occasional tramp iron.
Typical Examples of applications are;
- Removal of ferrous in mining operations.
- Separation of ferrous contamination in quarries.
- Magnetic extraction of ferrous particles in wood processing.
- Protecting crushing & grinding machinery.
Master Magnets can supply suspension magnets to operate over 450mm - 2000mm conveyor belt widths. For belt widths less than 450mm, Master Magnets would recommend a Plate Magnet as a more cost-effective solution.
Permanent Suspension Magnets
Permanent units are designed to remove general tramp ferrous metals from a range of conveyed materials. For applications that may require the extraction of small ferrous contaminants such as nails and screws, the Mastermag range of permanent suspension magnets can incorporate a tri-polar magnet design with core, poles and a backbar in high permeability mild steel. The tri-polar design ensures that magnetic flux leakage is reduced and the magnetic field is focused directly onto the centre of the conveyor belt to improve the extraction.
Electro Suspension Magnets
For applications that require the extraction of much larger tramp metals at higher operating gaps, Master Magnets manufacture one of the worlds widest ranges of Electro Magnets. Electro magnets can be either air or oil cooled depending on a customers specific requirements. The oil cooled magnets are fitted with a conservator tank to ensure that the coil is always oil immersed. The magnet is also complete with breather and sight glass.
Suspension magnets can be accompanied by a geared trolley. The trolleys can be fitted to existing support structures to allow the magnet to be moved aside from the conveyor for the manual removal of ferrous materials.
