The device rod magnetic is based on the use of neodymium magnets, which are placed in a casing made of stainless steel usually AISI304. As a result, it is possible to effectively remove ferromagnetic elements from different substances. An important element of its operation is the use of repulsion of N and S poles of neodymium magnets, which allows magnetic substances to be attracted. The thickness of the embedded magnet and its structure pitch affect the power and range of the separator's operation.

Generally speaking, magnetic separators are designed to extract ferromagnetic elements. If the cans are made of ferromagnetic materials, the separator will effectively segregate them. However, if the cans are made of non-ferromagnetic materials, such as aluminum, the separator will not be able to separate them.

Yes, magnetic rollers find application in the food sector for the elimination of metallic contaminants, such as iron fragments or iron dust. Our rods are made from acid-resistant steel, AISI 304, suitable for contact with food.

Magnetic rollers, often called magnetic separators, find application in food production, metal separation as well as waste processing. They help in eliminating iron dust in the course of the process of separating metals from other wastes.

Our magnetic rollers are built with neodymium magnets placed in a tube made of stainless steel with a wall thickness of 1mm.

Both ends of the magnetic bar will be with M8 threaded holes - 18 mm, enabling quick installation in machines or magnetic filter drawers. A "blind" version is also possible in manual separators.

In terms of features, magnetic bars stand out in terms of magnetic force lines, flux density and the area of operation of the magnetic field. We produce them in two materials, N42 and N52.

Generally it is believed that the stronger the magnet, the more effective. Nevertheless, the effectiveness of the magnet's power depends on the height of the used magnet and the quality of the material [N42] or [N52], as well as on the area of application and expected needs. The standard operating temperature of a magnetic bar is 80°C.

In the case where the magnet is more flat, the magnetic force lines will be short. On the other hand, in the case of a thicker magnet, the force lines are longer and reach further.

For constructing the casings of magnetic separators - rollers, usually stainless steel is utilized, especially types AISI 316, AISI 316L, and AISI 304.

In a salt water contact, type AISI 316 steel is recommended thanks to its excellent anti-corrosion properties.

Magnetic rollers are characterized by their specific arrangement of poles and their capability to attract magnetic substances directly onto their surface, as opposed to other devices that often use more complicated filtration systems.

Technical designations and terms pertaining to magnetic separators include among others polarity, magnetic induction, magnet pitch, as well as the type of steel used.

Magnetic induction for a magnet on a roller is determined using a teslameter or a gaussmeter with a flat Hall-effect probe, seeking the highest magnetic field value near the magnetic pole. The outcome is checked in a value table - the lowest is N30. All designations less than N27 or N25 indicate recycling that falls below the standard - they are not suitable.

Neodymium magnetic bars offer many advantages, including excellent separation efficiency, strong magnetic field, and durability. Disadvantages may include higher cost compared to other types of magnets and the need for regular maintenance.

By ensuring proper maintenance of neodymium magnetic rollers, it is recommended regularly cleaning them from contaminants, avoiding high temperatures up to 80°C, and shielding them from moisture if the threads are not sealed – in ours, they are. The rollers feature waterproofing IP67, so if they are leaky, the magnets inside can oxidize and weaken. Testing of the rollers is recommended be carried out once every 24 months. Caution should be taken during use, as it’s possible getting pinched. If the protective tube is only 0.5 mm thick, it may wear out, which in turn could cause problems with the magnetic rod seal and product contamination. The effective range of the roller is equal to its diameter: fi25mm gives an active range of about 25mm, while fi32 gives an active range of about 40mm.

Magnetic rollers are cylindrical neodymium magnets placed in a casing made of corrosion-resistant stainless steel, which are used to remove metal contaminants from bulk and granular materials. They are applied in industries such as food processing, ceramics, and recycling, where the removal of iron metals and iron filings is essential.

Advantages as well as 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 about 10 years, their strength decreases by only ~1% (theoretically),
They are extremely resistant to demagnetization by external magnetic sources,
Thanks to the shiny finish and nickel, gold, or silver coating, they have 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 significant 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.
Wide application in advanced technologically fields – are utilized in computer drives, electric drive mechanisms, medical apparatus or other advanced devices.

Disadvantages of neodymium magnets:

They are prone to breaking as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Potential hazard arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the context of children's health. It's also worth noting that small elements of these magnets can complicate diagnosis when they are in the body.

Handle Neodymium Magnets with Caution

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

Remember that 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.

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.

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

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

Magnets attract each other within a distance of several to about 10 cm from each other. Remember not to place fingers between magnets or in their path when they attract. Depending on how huge the neodymium magnets are, they can lead to a cut or a fracture.

Keep neodymium magnets away from 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.

Magnets made of neodymium are incredibly delicate, they easily crack as well as can become damaged.

Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnetic 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.

Make sure not to bring neodymium magnets close to the 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Avoid contact with neodymium magnets if you have a nickel 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and 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.
