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, 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 example, 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 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. Thanks to its sealed housing made of stainless steel, ensuring long-lasting and effective operation in various industries.

These devices are used for removing any iron contaminants, such as metal balls, 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.

Their application allows for the effective removal of iron contaminants from transported materials, especially in industrial sectors requiring precise contaminant separation. 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 as well as disadvantages of neodymium magnets NdFeB.

In addition to their pulling strength, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
They are extremely resistant to demagnetization caused by external magnetic sources,
In other words, due to the metallic silver coating, the magnet obtains an stylish appearance,
Magnetic induction on the surface of these magnets is impressively powerful,
These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to profile),
With the option for fine forming and personalized design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
Key role in advanced technical fields – they are used in data storage devices, rotating machines, healthcare devices and other advanced devices,
Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in tiny dimensions, which makes them useful in miniature devices

Disadvantages of rare earth magnets:

They can break when subjected to a heavy impact. If the magnets are exposed to mechanical hits, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from damage and additionally strengthens its overall durability,
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 structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Magnets exposed to moisture can oxidize. Therefore, for outdoor applications, we suggest waterproof types made of rubber,
Limited ability to create complex details in the magnet – the use of a housing is recommended,
Health risk related to magnet particles may arise, in case of ingestion, which is significant in the context of child safety. Furthermore, miniature parts from these devices have the potential to hinder health screening once in the system,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Handle with Care: Neodymium Magnets

Dust and powder from neodymium magnets are 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 magnetic are extremely fragile, leading to breaking.

Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnetic 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.

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

Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.

Keep neodymium magnets away from GPS and smartphones.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Keep neodymium magnets away from 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.

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 are the strongest magnets ever invented. Their strength can surprise 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.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

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, 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.

Neodymium magnets can become demagnetized 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.

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

Magnets will bounce and also clash together within a distance of several to almost 10 cm from each other.

Warning!
