The magnetic separator, namely the magnetic roller, uses the power of neodymium magnets, which are placed in a casing made of stainless steel usually AISI304. In this way, it is possible to precisely separate ferromagnetic elements from other materials. A key aspect of its operation is the repulsion of magnetic poles N and S, which enables magnetic substances to be attracted. The thickness of the magnet and its structure pitch determine the power and range of the separator's operation.

Generally speaking, magnetic separators are designed to segregate ferromagnetic particles. 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 be able to separate them.

Yes, magnetic rollers are employed in the food sector to clear metallic contaminants, including iron fragments or iron dust. Our rollers are constructed from durable acid-resistant steel, EN 1.4301, intended for use in food.

Magnetic rollers, often called magnetic separators, are used in food production, metal separation as well as recycling. They help in extracting iron dust during the process of separating metals from other wastes.

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

From both sides of the magnetic bar can be with M8 threaded openings, which enables 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 flux density, magnetic force lines and the area of operation of the magnetic field. We produce them in materials, N42 as well as N52.

Often it is believed that the stronger the magnet, the more efficient it is. However, the strength of the magnet's power is dependent 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.

When the magnet is more flat, the magnetic force lines will be short. By contrast, when the magnet is thick, the force lines are extended and extend over a greater distance.

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

In a salt water environment, AISI 316 steel is recommended thanks to its excellent corrosion resistance.

Magnetic bars stand out for their specific arrangement of poles and their ability to attract magnetic substances directly onto their surface, as opposed to other separators that may utilize more complicated filtration systems.

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

Magnetic induction for 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 result is verified in a value table - the lowest is N30. All designations less than N27 or N25 indicate recycling that doesn't meet the standard - they are not suitable.

Neodymium magnetic rollers offer a range of benefits such as higher attracting power, longer lifespan, and effectiveness in separating fine metal particles. Disadvantages may include higher cost compared to other types of magnets and the need for regular maintenance.

To properly maintain of neodymium magnetic rollers, you should regularly cleaning them from contaminants, avoiding high temperatures up to 80°C, and protecting them from moisture if the threads are not sealed – in ours, they are. The rollers our rollers have waterproofing IP67, so if they are not sealed, the magnets inside can oxidize and weaken. Magnetic field measurements should be carried out once every 24 months. Care should be taken, as there is a risk of finger injury. If the protective tube is only 0.5 mm thick, it may wear out, which in turn could lead to problems with the magnetic rod seal and product contamination. The effective range of the roller corresponds 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, 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 their strong holding force, neodymium magnets have these key benefits:

They virtually do not lose power, because even after 10 years, the performance loss is only ~1% (according to literature),
They protect against demagnetization induced by external electromagnetic environments effectively,
Because of the lustrous layer of silver, the component looks aesthetically refined,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
With the option for customized forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving design adaptation,
Important function in modern technologies – they are used in computer drives, rotating machines, diagnostic apparatus or even other advanced devices,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of magnetic elements:

They may fracture when subjected to a strong impact. If the magnets are exposed to physical collisions, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time increases its overall strength,
They lose field intensity at elevated temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of plastic for outdoor use,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is difficult,
Potential hazard related to magnet particles may arise, when consumed by mistake, which is notable in the health of young users. Moreover, tiny components from these products have the potential to complicate medical imaging if inside the body,
High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which can restrict large-scale applications

Be Cautious with Neodymium Magnets

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

Neodymium magnets can become demagnetized at high temperatures.

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

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.

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

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

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

Neodymium magnets are extremely fragile, resulting in their cracking.

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. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.

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

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.

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.

Neodymium magnets should not be near people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.

Keep neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Pay attention!

So that know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous strong neodymium magnets.
