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, 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. 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. The stainless steel housing protects the magnets, the device is durable and reliable in harsh industrial conditions.

These devices are used for removing any iron contaminants, such as balls with a diameter of 5-10 mm, M5-M10 nuts, iron nails. 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.

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. 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 as well as disadvantages of neodymium magnets NdFeB.

In addition to their tremendous magnetic power, neodymium magnets offer the following advantages:

Their power is maintained, and after around 10 years, it drops only by ~1% (according to research),
They show strong resistance to demagnetization from external field exposure,
The use of a mirror-like nickel surface provides a eye-catching finish,
Magnetic induction on the surface of these magnets is impressively powerful,
Thanks to their enhanced temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
The ability for custom shaping or adjustment to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which extends the scope of their use cases,
Wide application in cutting-edge sectors – they are utilized in data storage devices, rotating machines, healthcare devices or even high-tech tools,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of rare earth magnets:

They are prone to breaking when subjected to a strong impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time increases its overall robustness,
Magnets lose pulling force 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,
Magnets exposed to damp air can rust. Therefore, for outdoor applications, we advise waterproof types made of rubber,
The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is not feasible,
Potential hazard related to magnet particles may arise, in case of ingestion, which is significant in the health of young users. Moreover, miniature parts from these devices might complicate medical imaging after being swallowed,
High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications

Handle Neodymium Magnets with Caution

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

Neodymium magnets produce 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 damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

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

Maintain neodymium magnets far from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

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.

If you have a finger between or on the path of attracting magnets, there may be a severe cut or a fracture.

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

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. 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 are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can shock you.

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.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Keep neodymium magnets as far away as possible from 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.
