Magnetic beams are components mounted above conveyor systems, which use neodymium magnets to capture unwanted iron elements. Any metal parts are attracted to the underside of the beam. Magnetic beams are widely used in the food industry, 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 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. Custom-sized beams are available upon request.

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. Thanks to its sealed housing made of stainless steel, 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, bolts and nuts, metal items, such as nails or keys. The range of the beam's action depends on its magnetic parameters and cross-section. 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 ensure high reliability and work efficiency. 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 magnetic power, neodymium magnets offer the following advantages:

They retain their full power for around ten years – the loss is just ~1% (in theory),
They remain magnetized despite exposure to strong external fields,
The use of a mirror-like nickel surface provides a eye-catching finish,
The outer field strength of the magnet shows elevated magnetic properties,
Thanks to their high temperature resistance, they can operate (depending on the form) 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 usage potential,
Important function in cutting-edge sectors – they are used in computer drives, electric motors, clinical machines and high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer strong power in compact dimensions, which makes them ideal in compact constructions

Disadvantages of neodymium magnets:

They are fragile when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage while also strengthens its overall durability,
Magnets lose power 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 damp environment – during outdoor use, we recommend using waterproof magnets, such as those made of polymer,
Limited ability to create complex details in the magnet – the use of a external casing is recommended,
Potential hazard due to small fragments may arise, especially if swallowed, which is crucial in the protection of children. It should also be noted that small elements from these assemblies might complicate medical imaging once in the system,
In cases of mass production, neodymium magnet cost is a challenge,

Handle Neodymium Magnets with Caution

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

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

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

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

Neodymium magnets can become demagnetized at high temperatures.

While Neodymium magnets can lose their magnetic properties 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 joining of neodymium magnets is not under control, then they may crumble and also crack. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.

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

Magnets should not be treated as toys. Therefore, it is not recommended for 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.

Neodymium magnets are extremely fragile, they easily crack as well as can crumble.

Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable 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.

Neodymium magnets should not be near 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.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Under no circumstances should neodymium magnets be brought close to 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.

Pay attention!
