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. The use of such beams is particularly common in the food industry, mineral raw materials and other industrial sectors.
The selection of the magnetic beam depends on the width of the conveyor and the cross-section of the beam. The larger the cross-section of the beam, the greater the magnetic field range. For instance, for loose materials with a depth of 2-3 cm, a beam with a cross-section of 80x40 mm will suffice, whereas 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 magnetic beam works due to the use of neodymium magnets, which generate a magnetic field attracting metal elements. Metal objects are lifted and attach to the underside of the beam. The beam can be mounted above the conveyor or set at an angle as a chute separator. The stainless steel housing protects the magnets, the device is durable and reliable in harsh industrial conditions.
Magnetic beams effectively capture iron elements, such as balls with a diameter of 5-10 mm, bolts and nuts, iron nails. 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.
Their application allows for the effective removal of iron contaminants from transported materials, especially in industrial sectors requiring precise contaminant separation. Thanks to their design and strong neodymium magnets guarantee effectiveness in challenging industrial conditions. 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.

In addition to immense strength, neodymium magnets have the following advantages:

  • They do not lose power over time. After about 10 years, their strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic sources extremely well,
  • In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
  • They have very high magnetic induction on the surface of the magnet,
  • Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
  • Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes or sizes, which expands the range of their possible uses.
  • Significant importance in modern technologies – are utilized in computer drives, electric drive mechanisms, medical devices or very modern machines.

Disadvantages of neodymium magnets:

  • They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the form and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
  • 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,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Possible danger to health from tiny fragments of magnets can be dangerous, if swallowed, which is crucial in the context of child safety. It's also worth noting that tiny parts of these products are able to hinder the diagnostic process after entering the body.

Caution with Neodymium Magnets

Keep neodymium magnets as far away as possible from GPS and smartphones.

Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnetic are highly susceptible to damage, leading to shattering.

Magnets made of neodymium are fragile as well as will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

If you have a nickel allergy, avoid contact with neodymium magnets.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Keep neodymium magnets away from people with pacemakers.

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

  Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.

Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

If the joining of neodymium magnets is not controlled, then they may crumble and crack. You can't move them to each other. At a distance less than 10 cm you should have them extremely strongly.

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.

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

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can shock you at first.

Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.
