Magnetic beams are components mounted above conveyor systems, which are based on strong neodymium magnets to separate iron contaminants from the transported material. Metallic elements float up and attach to the bottom surface of the beam. Magnetic beams are widely used in the food industry, plastic processing and other industrial sectors.

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, 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, ensuring long-lasting and effective operation in various industries.

Magnetic beams effectively capture iron elements, such as balls with a diameter of 5-10 mm, bolts and 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. Thanks to this, magnetic beams are effective in metal separation in industries such as recycling, food processing, and plastic processing.

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. Additionally, 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.

Apart from immense strength, neodymium magnets have the following advantages:

They do not lose power over time - after about 10 years, their power decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic sources very well,
In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an visually attractive appearance,
They have very high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
Key role in modern technologies – are used in hard drives, electric motors, medical equipment or very modern machines.

Disadvantages of neodymium magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
Magnets lose their strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the shape and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Possible danger associated with microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices can complicate diagnosis in case of swallowing.

Precautions

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.

Neodymium magnets are extremely delicate, they easily break and can crumble.

Magnets made of neodymium are delicate and 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.

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 also touch together within a distance of several to almost 10 cm from each other.

Neodymium magnets should not be around youngest children.

Remember that 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.

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

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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets are the most powerful magnets ever invented. Their strength 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 damage to the magnets.

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

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.

Dust and powder from neodymium magnets are highly 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.

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.

In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Be careful!

In order for you to know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
