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. 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 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 magnetic beam works due to the use of 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.

These devices are used for removing any iron contaminants, such as metal balls, 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. 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 their remarkable pulling force, neodymium magnets offer the following advantages:

They retain their full power for nearly ten years – the drop is just ~1% (in theory),
They show exceptional resistance to demagnetization from outside magnetic sources,
By applying a bright layer of silver, the element gains a sleek look,
Magnetic induction on the surface of these magnets is impressively powerful,
Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
With the option for tailored forming and targeted design, these magnets can be produced in numerous shapes and sizes, greatly improving application potential,
Wide application in modern technologies – they find application in computer drives, electromechanical systems, medical equipment as well as sophisticated instruments,
Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in compact dimensions, which makes them ideal in small systems

Disadvantages of neodymium magnets:

They can break when subjected to a sudden impact. If the magnets are exposed to mechanical hits, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and enhances its overall strength,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (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,
They rust in a moist environment – during outdoor use, we recommend using encapsulated magnets, such as those made of non-metallic materials,
The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is not feasible,
Safety concern linked to microscopic shards may arise, if ingested accidentally, which is crucial in the health of young users. Moreover, small elements from these products might hinder health screening if inside the body,
Due to expensive raw materials, their cost is considerably higher,

Precautions with Neodymium Magnets

The magnet is coated with nickel - be careful 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.

Keep neodymium magnets as far away as possible from 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.

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 fragile as well as can easily crack as well as get damaged.

Magnets made of neodymium are delicate as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. 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 not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

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

Magnets may crack or alternatively crumble with careless joining to each other. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.

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

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

The strong magnetic field generated by neodymium magnets can destroy 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. Remember not to place neodymium magnets close to these electronic devices.

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

Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
