The magnetic separator, namely the magnetic roller, uses the force of neodymium magnets, which are welded in a casing made of stainless steel usually AISI304. In this way, it is possible to efficiently segregate ferromagnetic elements from other materials. A fundamental component of its operation is the use of repulsion of N and S poles of neodymium magnets, which causes 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 segregate ferromagnetic elements. If the cans are made from ferromagnetic materials, a magnetic separator will be effective. 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 food production to clear metallic contaminants, for example iron fragments or iron dust. Our rods are made from durable acid-resistant steel, AISI 304, approved for use in food.

Magnetic rollers, otherwise cylindrical magnets, are employed 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 materials.

Our magnetic rollers consist of neodymium magnets anchored in a stainless steel tube cylinder 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 simple mounting in machines or magnetic filter drawers. A "blind" version is also possible in manual separators.

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

Usually it is believed that the greater the magnet's power, the better. But, the value of the magnet's power is based 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. By contrast, in the case of a thicker magnet, the force lines will be extended and extend over a greater distance.

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

In a salt water environment, type AISI 316 steel is highly recommended due to its outstanding anti-corrosion properties.

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

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

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 outcome 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 bars 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 the requirement for frequent cleaning, greater weight, and potential installation difficulties.

For proper maintenance of neodymium magnetic rollers, you should regularly cleaning them from contaminants, avoiding extreme temperatures up to 80°C, and shielding them from moisture if the threads are not sealed – in ours, they are. The rollers our rollers have waterproofing IP67, so if they are leaky, the magnets inside can rust and lose their power. Testing of the rollers is recommended 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 lead to 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, 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 and disadvantages of neodymium magnets NdFeB.

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years, the performance loss is only ~1% (according to literature),
They remain magnetized despite exposure to magnetic noise,
By applying a reflective layer of silver, the element gains a sleek look,
They have extremely strong magnetic induction on the surface 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 shape),
The ability for accurate shaping and adjustment to individual needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
Significant impact in modern technologies – they are utilized in data storage devices, electromechanical systems, medical equipment and sophisticated instruments,
Thanks to their power density, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to external force, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture and additionally strengthens its overall durability,
High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on shape). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of rubber for outdoor use,
Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
Possible threat due to small fragments may arise, if ingested accidentally, which is significant in the context of child safety. It should also be noted that minuscule fragments from these magnets have the potential to interfere with diagnostics once in the system,
In cases of tight budgets, neodymium magnet cost is a challenge,

Handle Neodymium Magnets with Caution

The magnet is coated with nickel. Therefore, exercise caution 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 GPS and smartphones.

Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

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

Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to place fingers between magnets or alternatively in their path when attract. Magnets, depending on their size, are able even cut off a finger or there can be a significant pressure or even a fracture.

Magnets are not toys, children should not play with them.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. 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 among the most powerful magnets on Earth. The astonishing force they generate between each other can surprise you.

To handle 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.

Neodymium magnets are noted for being fragile, which can cause them to shatter.

Neodymium magnets are extremely delicate, and by joining them in an uncontrolled manner, they will crack. 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.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

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.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

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