A magnetic beam is a device mounted above conveyor belts, which are based on strong neodymium magnets to capture unwanted iron elements. Metallic elements float up and attach to the bottom surface of the beam. Magnetic beams are widely used in recycling, mineral raw materials and other industrial sectors.

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 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. 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. This causes all metals in the transport to be captured and stopped. 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.

Magnetic beams effectively capture iron elements, such as balls with a diameter of 5-10 mm, 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, which is crucial in industries such as food processing, recycling, plastic processing, and mineral raw materials. Thanks to their design and strong neodymium magnets guarantee effectiveness in challenging industrial conditions. 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 their power (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They have very high magnetic induction on the surface of the magnet,
By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
Significant importance in modern technologies – find application in hard drives, electric drive mechanisms, medical equipment or other advanced devices.

Disadvantages of neodymium magnets:

They can break as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
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
Potential hazard associated with microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of children's health. Additionally, small elements of these magnets are able to be problematic in medical diagnosis after entering the body.

Precautions

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 away from people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

Neodymium magnets are fragile as well as can easily break and get damaged.

Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crack. 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.

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

Neodymium magnets produce strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or alternatively a fracture.

It is essential to maintain neodymium magnets away from children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets can demagnetize at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can shock you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.

Avoid bringing neodymium magnets close to a phone or GPS.

Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
