Electro 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.
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.
Electro Overband Magnets
The Heavy-Duty electro overband is the most powerful overband separator from the Mastermag range. Master Magnets manufacture the widest range of this type of separator, with the largest weighing 35 tonnes and spanning across a 2 metre wide conveyor.
Due to its high magnetic strength, the overband is able to work at an increased operating gap, enabling it to extract ferrous from deep troughed conveyors.
Electro magnetic overbands are commonly used for installation in plants within the quarrying and recycling industries where they would be positioned either inline over the head pulley or across a conveyor belt.
Master Magnets supply Heavy-Duty overband magnets to operate over 150mm – 2000mm conveyor belts. For larger conveyor belt widths, overband magnets can be custom designed to suit the application. Additional support structures can also be supplied.
There are two different types of heavy-duty electro overbands;
- Oil cooled – This type of heavy-duty overband is the most commonly used of the two types. It efficiently maintains an optimum working temperature and is also capable of producing a higher magnetic force than the equivalent air cooled electro overband magnet.
- Air cooled – This type of magnet is used where oil is not a customers preference for health and safety reasons. For example, a client may wish to use this type of cooling because it is less of a fire hazard.
To give the overband magnet a longer belt life (especially when handling abrasive materials) an armoured belt can be fitted as an optional extra.
Heat resistant belting can also be supplied to allow the heavy-duty overband to operate at higher ambient temperatures.
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.
