The device rod magnetic is based on the use of neodymium magnets, which are placed in a construction made of stainless steel usually AISI304. As a result, it is possible to effectively segregate ferromagnetic elements from the mixture. A key aspect of its operation is the use of repulsion of N and S poles of neodymium magnets, which enables magnetic substances to be collected. The thickness of the magnet and its structure's pitch affect the power and range of the separator's operation.

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

Yes, magnetic rollers are employed in the food industry to clear metallic contaminants, such as iron fragments or iron dust. Our rollers are built from acid-resistant steel, EN 1.4301, intended for use in food.

Magnetic rollers, otherwise magnetic separators, are employed in food production, metal separation as well as waste processing. They help in removing iron dust during the process of separating metals from other wastes.

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

From both sides of the magnetic bar can be with M8 threaded holes - 18 mm, allowing for easy installation in machines or magnetic filter drawers. A "blind" version is also possible in manual separators.

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

Often it is believed that the stronger the magnet, the more effective. But, 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 use and anticipated needs. The standard operating temperature of a magnetic bar is 80°C.

If 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 extend over a greater distance.

For constructing the casings of magnetic separators - rollers, frequently stainless steel is used, particularly types AISI 316, AISI 316L, and AISI 304.

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

Magnetic rollers are characterized by their unique configuration of poles and their capability to attract magnetic particles directly onto their surface, as opposed to other devices that often use complex filtration systems.

Technical designations and terms related to magnetic separators comprise amongst others polarity, magnetic induction, magnet pitch, as well as the type of steel used.

Magnetic induction for a magnet on a roller is measured using a teslameter or a gaussmeter with a flat Hall-effect probe, aiming to find the highest magnetic field value close to the magnetic pole. The result is checked in a value table - the lowest is N30. All designations below N27 or N25 suggest recycling that doesn't meet the standard - they are not suitable.

Neodymium magnetic rollers offer a range of benefits such as a very strong magnetic field, the ability to capture even the tiniest metal particles, and durability. On the other hand, among the drawbacks, one can mention higher cost compared to other types of magnets and the need for regular maintenance.

To properly maintain of neodymium magnetic rollers, it is recommended regularly cleaning them from deposits, 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 not sealed, the magnets inside can rust and weaken. Testing of the rollers should be carried out every two years. Care should be taken, as there is a risk 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.

A magnetic roller is a magnetic separator made from a neodymium magnet enclosed in a cylindrical stainless steel housing, used for separating ferromagnetic contaminants from raw materials. They are applied in industries such as food processing, ceramics, and recycling, where metal separation is crucial.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense strength, neodymium magnets have the following advantages:

They do not lose their strength (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
They are highly resistant to demagnetization by external magnetic sources,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They possess 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...
Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
Key role in the industry of new technologies – are utilized in HDD drives, electric motors, medical devices or various technologically advanced devices.

Disadvantages of neodymium magnets:

They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts, and at the same time 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 reduction 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,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
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
Health risk to health from tiny fragments of magnets are risky, if swallowed, which becomes significant in the context of children's health. Furthermore, tiny parts of these products have the potential to be problematic in medical diagnosis when they are in the body.

Handle Neodymium Magnets Carefully

Do not give neodymium magnets to youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Magnets will crack or alternatively crumble with uncontrolled connecting to each other. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.

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 not recommended for people with pacemakers.

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

Neodymium magnetic are fragile as well as can easily crack as well as shatter.

Magnets made of neodymium are fragile as well as will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.

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

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 among the most powerful magnets on Earth. The surprising force they generate between each other can shock you.

To use 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.

The magnet is coated with nickel - be careful if you have an 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets as far away as possible from 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.

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.

Caution!
