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. The Mastermag range of plate magnets are constructed from a magnetic stainless steel casing, which utilises projected magnetic stainless steel poles for an 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.
To extract metal from deeper burdens and increased throughput rates Master Magnets can also provide a dual deep field separator. All plate magnets are virtually maintenance free, offering a long service life not affected by wet conditions.
The plate magnets are a manually cleaned solution and are often used in similar applications to the suspension magnet but on a smaller scale.
The suspension magnet can be used for extracting metals on belt widths between 450mm to 2000mm. If the belt width is less than 450mm wide, then a plate magnet would be a more suitable alternative.
The Standard Plate Magnet
The standard plate magnet is the most commonly used unit from the Plate magnet range. The magnet itself is made from strontium ferrite and has a stainless steel casing with projected magnetic poles. The strontium ferrite units are suitable for picking up ferrous contaminants such as nuts, bolts, nails and screws.
The Rare Earth Plate Magnet
The rare earth plate magnet is made from neodymium iron boron, which generates an extremely high magnetic intensity. This particular model is used for specialised applications such as the removal of fine iron particles from powders and food stuffs. An optional tapered pole can be fitted to the rare earth plate magnet, which ensures that any extracted ferrous contamination does not get pulled back into the product stream.
The Dual Deep Field Magnet
The dual deep field magnet is used to extract metals from deeper burdens and high throughput rates. With two powerful magnetic plates located at either side of a housing, the free falling product stream is fed through the top of the magnet and directed towards the plate surface by a diverter plate. Any ferrous materials are extracted by either of the magnets leaving a clean end product.
Diagonal Leg Plate Magnet
The diagonal leg plate magnet consists of two individual magnetic plates that are fitted into a diagonal leg arrangement. This particular model can provide double separation for when ferrous contamination may be trapped beneath a product burden.
