Permanent Suspension 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.
Bunting have increased their range of Suspension Magnets over the years to cater for the ever-increasing size of conveyors, deeper troughing and conveyor speeds. Bunting can offer customers two types of suspension magnet, depending on specific application 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 re-positioned 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.
Bunting can supply suspension magnets to operate over 450mm – 2000mm conveyor belt widths. For belt widths less than 450mm, Bunting 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 Bunting range of permanent suspension magnets can incorporate a tri-polar magnet design with core, poles and a back bar 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.
Geared Trolley: allow the magnet to be moved aside from the conveyor for the manual removal of ferrous materials.
Rubber Stripper Sheet: A heavy-duty rubber belt is fitted to one end of the magnet and is wrapped around the working face and attached, under tension, to a pulley on the other end of the magnet. Accumulated tramp iron is easily removed from the working face by simply drawing the belt back underneath the magnet.
Steel Stripper Tray: A stainless steel stripper tray is fitted beneath the magnet on slide rails. Accumulated tramp iron is easily removed from the working face by simply removing the tray.
