Magnetic beams, also called blocks, are cubical and they are designer for food industry. They are also successfully used for detecting iron pellets from all loose materials, for example aggregates, fragmented non-ferrous metals. The mounting method depends on the expectations and technical conditions. Usually, they are hung over the conveyor. Neodymium magnetic beams made by HSMAG are, according to the clients, the best separator for detecting undesired iron items in transported food (fruit, vegetables, tobacco etc.). These magnetic separators are used in almost every industry, including recycling.
A magnetic beam mounted above a belt conveyor is used for catching of undesirable steel or iron elements from transported substances (food industry, processing of plastics, mineral raw materials, recycling, etc.). Mounted at a angle, can also be used as a chute separator. Watertight housing made of acid-proof steel 304#, 301# contains a magnetic circuit with neodymium magnets. It is a bottom surface of the beam which is magnetic active. The beam’s both ends are equipped with two threaded apertures M10 (spaced 60 mm) for mounting.
We manufacture magnetic beams adapted both to be mounted over the conveyor and to be installed at the end of the conveyor belt where the material pours over the surface of the beam.
In the first case lower surface is magnetically active. In the second case two surfaces – lower and side – are magnetically active. Owing to this, the poured material is not slowed down by the impurities of the separator because they stick to the side surface. Cascade threshold separators are used in areas where there are big movements of foods and relatively big mount of impurities.
Mangetic beams are made of welded austenitic steel. The source of magnetic field are usually high-energy neodymium magnets. It is also possible to manufacture separators from cheaper ceramic magnets – ferrite. We recommend to install magnetic beams with sintered neodymium magnets (NdFeB), because their ratio of emitted energy in proportion to the mass is substantially higher.
The hit of the last season were neodymium magnets constructed in the same way as magnetic beams used during underwater explorations. In our online shop you can find new models of magnets intended for treasure hunters designed by the head of the design department of HSMAG.
On commission we are ready to provide magnetic separators with dimensions chosen by Clients. Magnetic parameters, range of activity and dimensions are adjusted according to Client needs and expectations.
Magnetic field in the center of surface between the magnetic poles (maximum) is ~0,7 [T] = 7000 [Gs].
As an example, range of catching for different caught objects: balls Ø5-10 – approx.70 mm, screw caps M5-M10 – approx.80 mm, flat spanner – approx.100 mm, iron nails 2”-3,5” – approx.120mm.
In the magnetic beam sintered neodymium magnets were used. The maximal working temperature for the magnetic separators with neodymium magnets is approx. 80°[C].
