Magnetic beams are components mounted above conveyor systems, 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. The use of such beams is particularly common in recycling, mineral raw materials 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 create a field capable of attracting iron contaminants. Metal objects are lifted and attach to the underside of the beam. Mounted at the right angle, it can function as a chute separator. The stainless steel housing protects the magnets, ensuring long-lasting and effective operation in various industries.

These devices are used for removing any iron contaminants, 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. 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. 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 and disadvantages of neodymium magnets NdFeB.

In addition to their exceptional strength, neodymium magnets offer the following advantages:

They do not lose their even during approximately ten years – the reduction of strength is only ~1% (based on measurements),
Their ability to resist magnetic interference from external fields is among the best,
Thanks to the polished finish and silver coating, they have an aesthetic appearance,
The outer field strength of the magnet shows advanced magnetic properties,
Thanks to their enhanced temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
Thanks to the flexibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in different geometries, which increases their functional possibilities,
Wide application in modern technologies – they find application in data storage devices, electric drives, healthcare devices along with technologically developed systems,
Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of neodymium magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and additionally reinforces its overall robustness,
Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a wet environment, especially when used outside, we recommend using waterproof magnets, such as those made of polymer,
Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing fine shapes directly in the magnet,
Safety concern due to small fragments may arise, especially if swallowed, which is crucial in the context of child safety. Moreover, small elements from these products may complicate medical imaging when ingested,
Due to a complex production process, their cost is relatively high,

Exercise Caution with Neodymium Magnets

Neodymium magnets are the strongest magnets ever created, and their power can surprise you.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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 holding a finger in the path of a neodymium magnet, in that situation, a cut or even a fracture may occur.

Neodymium magnets are delicate as well as can easily crack and shatter.

Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. 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.

Magnets are not toys, youngest should not play with them.

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.

Neodymium magnets are not recommended for people with pacemakers.

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.

The magnet is coated with nickel. Therefore, exercise caution if you have an allergy.

Studies show a small percentage of people have allergies to certain metals, including 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.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

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 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.

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.
