A magnetic beam is a device mounted above conveyor belts, which use neodymium magnets to separate iron contaminants from the transported material. Any metal parts are attracted to the underside of the beam. Magnetic beams are widely used in recycling, mineral raw materials and many other industries.

The selection of the magnetic beam depends on the width of the conveyor and the cross-section of the beam. 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. We also manufacture magnetic beams made to order according to customer requirements.

The basis of the magnetic beam’s operation are strong neodymium magnets, which generate a magnetic field attracting metal elements. Metal objects are lifted and attach to the underside of the beam. The beam can be mounted above the conveyor or set at an angle as a chute separator. The stainless steel housing protects the magnets, the device is durable and reliable in harsh industrial conditions.

Magnetic beams effectively capture iron elements, such as balls with a diameter of 5-10 mm, M5-M10 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.

Magnetic beams are indispensable in industry due to their effectiveness in metal separation, which is crucial in industries such as food processing, recycling, plastic processing, and mineral raw materials. Thanks to their design and strong neodymium magnets 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 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 protect against demagnetization caused by external magnetic field extremely well,
In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
They exhibit extremely 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 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.
Significant importance in modern technologies – are used in hard drives, electric drive mechanisms, medical apparatus or very advanced devices.

Disadvantages of neodymium magnets:

They are prone to breaking as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested 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 power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the form 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 suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Health risk to health from tiny fragments of magnets pose a threat, in case of ingestion, which is crucial in the context of child safety. Additionally, tiny parts of these devices have the potential to hinder the diagnostic process in case of swallowing.

Exercise Caution with Neodymium Magnets

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

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium magnets can become demagnetized at high temperatures.

While Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.

If have a finger between or alternatively on the path of attracting magnets, there may be a large cut or even a fracture.

Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

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

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

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.

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.

If you have a nickel allergy, avoid contact with neodymium magnets.

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.

Neodymium magnets are characterized by their fragility, which can cause them to shatter.

Neodymium magnetic are fragile and will shatter 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.

Caution!

In order to show why neodymium magnets are so dangerous, see the article - How very dangerous are very powerful neodymium magnets?.
