Magnetic beams are components mounted above conveyor systems, which are based on strong neodymium magnets to capture unwanted iron elements. Metallic elements float up and attach to the bottom surface of the beam. Magnetic beams are widely used in the food industry, 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 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. Custom-sized beams are available upon request.
The basis of the magnetic beam’s operation are strong neodymium magnets, which generate a magnetic field attracting metal elements. 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, M5-M10 nuts, iron nails. The range of the beam's action depends on its magnetic parameters and cross-section. Thanks to this, magnetic beams are effective in metal separation in industries such as recycling, food processing, and plastic processing.
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. 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 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 highly resistant to demagnetization by external magnetic field,
  • In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
  • They exhibit 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 and 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.
  • Key role in advanced technologically fields – find application in hard drives, electric motors, medical devices and very highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They can break as they are extremely 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 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,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Possible danger to health from tiny fragments of magnets pose a threat, when accidentally ingested, which is particularly important in the context of child safety. Furthermore, miniscule components of these products have the potential to hinder the diagnostic process after entering the body.

Handle Neodymium Magnets Carefully

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.

Neodymium magnets will bounce and touch together within a distance of several to almost 10 cm from each other.

Magnets made of neodymium are extremely fragile, resulting in shattering.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

  Neodymium magnets should not be in the vicinity youngest children.

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.

Avoid bringing neodymium magnets close to a phone or GPS.

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

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

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

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

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.

Neodymium magnets are not recommended for 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.

The magnet coating contains nickel, so be cautious 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.

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

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