Magnetic beams are components mounted above conveyor systems, which use neodymium magnets to capture unwanted iron elements. Metallic elements float up and attach to the bottom surface of the beam. The use of such beams is particularly common in the food industry, 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. The larger the cross-section of the beam, the greater the magnetic field range. For instance, 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. We also manufacture magnetic beams made to order according to customer requirements.

The magnetic beam works due to the use of neodymium magnets, which generate a magnetic field attracting metal elements. This causes all metals in the transport to be captured and stopped. 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.

Magnetic beams effectively capture iron elements, such as balls with a diameter of 5-10 mm, bolts and nuts, iron nails. 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, 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 remarkable strength, neodymium magnets offer the following advantages:

They do not lose their even during nearly ten years – the decrease of power is only ~1% (theoretically),
Their ability to resist magnetic interference from external fields is impressive,
By applying a reflective layer of silver, the element gains a modern look,
They possess intense magnetic force measurable at the magnet’s surface,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to build),
With the option for customized forming and precise design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
Wide application in modern technologies – they are used in hard drives, electric motors, healthcare devices and sophisticated instruments,
Thanks to their power density, small magnets offer high magnetic performance, in miniature format,

Disadvantages of NdFeB magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to external force, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks and strengthens its overall durability,
They lose field intensity at increased temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a humid environment. If exposed to rain, we recommend using encapsulated magnets, such as those made of polymer,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is not feasible,
Safety concern related to magnet particles may arise, if ingested accidentally, which is crucial in the protection of children. It should also be noted that minuscule fragments from these assemblies can interfere with diagnostics after being swallowed,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Handle Neodymium Magnets Carefully

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

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

Neodymium magnets generate 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 videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Do not give neodymium magnets to youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays 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.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Neodymium magnets will bounce and clash together within a distance of several to around 10 cm from each other.

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

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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

Neodymium magnets can become demagnetized 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.

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.

Neodymium magnetic are fragile as well as can easily crack as well as get damaged.

Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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 are not recommended for people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can 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.
