A magnetic beam is a device mounted above conveyor belts, which are based on strong 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, plastic processing and many other industries.
The dimensions of the magnetic beam are tailored to the width of the belt and the magnetic field range. The larger the cross-section of the beam, the greater the magnetic field range. For example, 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. Custom-sized beams are available upon request.
The basis of the magnetic beam’s operation are strong neodymium magnets, which create a field capable of attracting iron contaminants. This causes all metals in the transport to be captured and stopped. Mounted at the right angle, it can function as a chute separator. Thanks to its sealed housing made of stainless steel, ensuring long-lasting and effective operation in various industries.
Magnetic beams effectively capture iron elements, such as metal balls, M5-M10 nuts, iron nails. The magnetic field strength of the beam allows for capturing metals from a distance of up to 120 mm. Thanks to this, magnetic beams are effective in metal separation in industries such as recycling, food processing, and plastic processing.
Magnetic beams are indispensable in industry due to their effectiveness in metal separation, which is crucial in industries such as food processing, recycling, plastic processing, and mineral raw materials. Equipped with neodymium magnets, these beams 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.

Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose their strength (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic field,
  • In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an visually attractive appearance,
  • They have very high magnetic induction on the surface of the magnet,
  • By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
  • Significant importance in advanced technologically fields – find application in computer drives, electric drive mechanisms, medical equipment or various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the shape and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
  • Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Potential hazard associated with microscopic parts of magnets can be dangerous, when accidentally ingested, which becomes significant in the aspect of protecting young children. It's also worth noting that small elements of these magnets are able to complicate diagnosis in case of swallowing.

Be Cautious with Neodymium Magnets

Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

In the case of placing a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.

Magnets made of neodymium are incredibly delicate, they easily break and can crumble.

Magnets made of neodymium are fragile and will break 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. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Neodymium magnets can demagnetize at high temperatures.

Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Dust and powder from neodymium magnets are highly flammable.

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

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Avoid contact with neodymium magnets if you have a nickel allergy.

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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

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

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

  Do not give neodymium magnets to children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Avoid bringing neodymium magnets close to a phone or GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

To raise awareness of why neodymium magnets are so dangerous, see the article titled How dangerous are powerful neodymium magnets?.
