There are a variety of magnets that classify for industrial use. Industrial magnets are high strength magnets that have certain characteristics that make them ideal for applications in the industrial industry. Different applications require different types of industrial magnets.
Types of industrial magnets
Permanent overband magnets:
The overband separators are effective units for the continuous removal of tramp ferrous material from a product stream. This specific type of magnetic separator is used to protect, clean and separate materials on applications in the recycling and quarrying industries.
Permanent suspension magnets:
Suspension magnets are specially 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.
Drum magnets are constructed with a 180 degree stationary magnet system. Material is fed onto the drum cover at the leading point of the magnet section. Magnetic materials will adhere to the drum cover as it revolves and will then be discharged behind the normal trajectory.
Tube and grid magnets:
Tube and grid magnets are often used for the removal of fine and general tramp iron to protect a product from metal contamination. They are manufactured from ferrite or rare earth magnetic tubes, depending on a customer’s application requirements.
They are most commonly installed into hoppers, chutes and ducts, magnetic tubes and grids and are often used for applications in the food processing and ceramics industry.
Plate magnets are an inexpensive form of magnetic protection against occasional tramp iron contamination. The plate magnets can be used in a wide range of industries and are commonly installed within a chute or over a conveyor. Plate magnets are constructed from a magnetic stainless steel casing, which utilises projected magnetic stainless steel poles for enhanced field intensity.
Magnetic plates can be manufactured with either a strontium ferrite, or a high-intensity neodymium iron boron (rare earth) magnet system. The more powerful rare earth solution is advised for removing much finer iron particles from powders and foodstuffs.
