Magnetic beams are components mounted above conveyor systems, which are based on strong neodymium magnets to separate iron contaminants from the transported material. Metallic elements float up and attach to the bottom surface of the beam. Magnetic beams are widely used in recycling, plastic processing 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 instance, 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. The beam can be mounted above the conveyor or set at an angle as a chute separator. The stainless steel housing protects the magnets, ensuring long-lasting and effective operation in various industries.
Magnetic beams effectively capture iron elements, such as metal balls, bolts and nuts, metal items, such as nails or keys. The magnetic field strength of the beam allows for capturing metals from a distance of up to 120 mm. 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, which is crucial in industries such as food processing, recycling, plastic processing, and mineral raw materials. Equipped with neodymium magnets, these beams guarantee effectiveness in challenging industrial conditions. 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 as well as disadvantages of neodymium magnets NdFeB.

In addition to immense strength, 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 are extremely resistant to demagnetization by external magnetic field,
  • 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...
  • Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
  • Wide application in the industry of new technologies – are used in computer drives, electric motors, medical apparatus or other advanced devices.

Disadvantages of neodymium magnets:

  • They can break 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,
  • They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • 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 are risky, if swallowed, which is crucial in the aspect of protecting young children. It's also worth noting that tiny parts of these devices have the potential to be problematic in medical diagnosis after entering the body.

Safety Precautions

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.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

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

Neodymium magnets are fragile as well as can easily break as well as shatter.

Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

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.

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

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

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

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

 Keep neodymium magnets away from youngest children.

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.

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 can demagnetize at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

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