A magnetic beam is a device mounted above conveyor belts, which use neodymium magnets to capture unwanted iron elements. Any metal parts are attracted to the underside of the beam. The use of such beams is particularly common 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. Custom-sized beams are available upon request.
The magnetic beam works due to the use of 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 balls with a diameter of 5-10 mm, bolts and 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, especially in industrial sectors requiring precise contaminant separation. Thanks to their design and strong neodymium magnets ensure high reliability and work efficiency. Moreover, 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 strength, neodymium magnets have the following advantages:

  • They do not lose strength over time. After approximately 10 years, their power decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic field,
  • 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 shape) even at temperatures up to 230°C and above...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
  • Key role in the industry of new technologies – are used in HDD drives, electric drive mechanisms, medical devices and very modern machines.

Disadvantages of neodymium magnets:

  • They are fragile when subjected to a strong 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,
  • High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape 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,
  • Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
  • 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
  • Health risk arising from small pieces of magnets can be dangerous, if swallowed, which is crucial in the aspect of protecting young children. Additionally, tiny parts of these products can complicate diagnosis in case of swallowing.

We Recommend Caution with Neodymium Magnets

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

Neodymium magnetic are particularly fragile, resulting in damage.

Neodymium magnets 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. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can shock you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Neodymium magnets generate intense 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. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

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

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

  Neodymium magnets should not be around youngest children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

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.

Keep neodymium magnets away from GPS and smartphones.

Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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