A magnetic beam is a device mounted above conveyor belts, which use neodymium magnets to separate iron contaminants from the transported material. Any metal parts are attracted to the underside of the beam. Magnetic beams are widely used in recycling, mineral raw materials and other industrial sectors.
The dimensions of the magnetic beam are tailored to the width of the belt and the magnetic field range. A larger cross-section allows the beam to be suspended higher above the belt. For example, for loose materials with a depth of 2-3 cm, a beam with a cross-section of 80x40 mm will suffice, while for a layer of material over 8 cm, a larger beam is required. We also manufacture magnetic beams made to order according to customer requirements.
The basis of the magnetic beam’s operation are strong neodymium magnets, which generate a magnetic field attracting metal elements. Metal objects are lifted and attach to the underside of the beam. Mounted at the right angle, it can function as a chute separator. The stainless steel housing protects the magnets, the device is durable and reliable in harsh industrial conditions.
These devices are used for removing any iron contaminants, such as balls with a diameter of 5-10 mm, M5-M10 nuts, metal items, such as nails or keys. The range of the beam's action depends on its magnetic parameters and cross-section. These devices are indispensable in many industrial sectors where removing iron contaminants is critical.
Magnetic beams are indispensable in industry due to their effectiveness in metal separation, especially in industrial sectors requiring precise contaminant separation. Thanks to their design and strong neodymium magnets ensure high reliability and work efficiency. Additionally, the ability to customize the beam parameters to meet the specific requirements of the customer makes them a versatile solution for many industrial sectors.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense power, neodymium magnets have the following advantages:

  • They do not lose their power (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field extremely well,
  • By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
  • They have very high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
  • Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
  • Wide application in modern technologies – are utilized in HDD drives, electric drive mechanisms, medical apparatus and various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
  • They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Potential hazard to health from tiny fragments of magnets pose a threat, in case of ingestion, which becomes significant in the context of children's health. Additionally, small elements of these devices have the potential to complicate diagnosis when they are in the body.

Handle Neodymium Magnets Carefully

Keep neodymium magnets away from the wallet, computer, and TV.

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

The magnet coating contains nickel, so be cautious if you have a nickel allergy.

Studies show a small percentage of people have allergies to certain metals, including nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets can demagnetize at high temperatures.

Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.

Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a serious injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.

  Do not give neodymium magnets to youngest children.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Neodymium magnets are the most powerful magnets ever invented. Their power can surprise you.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.

Magnets made of neodymium are known for their fragility, which can cause them to shatter.

Magnets made of neodymium are delicate and will crack if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous powerful neodymium magnets.
