The main mechanism of the magnetic separator is the use of neodymium magnets, which are welded in a casing made of stainless steel usually AISI304. Due to this, it is possible to effectively separate ferromagnetic particles from different substances. A key aspect of its operation is the repulsion of N and S poles of neodymium magnets, which causes magnetic substances to be targeted. The thickness of the magnet and its structure pitch determine the range and strength of the separator's operation.

Generally speaking, magnetic separators are used to extract ferromagnetic particles. If the cans are made from ferromagnetic materials, the separator will be able to separate 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 used in the food sector to remove metallic contaminants, including iron fragments or iron dust. Our rods are made from durable acid-resistant steel, AISI 304, intended for contact with food.

Magnetic rollers, otherwise cylindrical magnets, are used in food production, metal separation as well as waste processing. They help in eliminating iron dust during the process of separating metals from other wastes.

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

Both ends of the magnetic bar can be with M8 threaded holes - 18 mm, which enables 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 flux density, magnetic force lines and the area of operation of the magnetic field. We produce them in materials, N42 and N52.

Often it is believed that the stronger the magnet, the more effective. However, the strength 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 more compressed. On the other hand, when the magnet is thick, the force lines are longer and extend over a greater distance.

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

In a saltwater environment, type AISI 316 steel is highly recommended thanks to its outstanding corrosion resistance.

Magnetic rollers stand out for 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 magnet pitch, polarity, and magnetic induction, 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, 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 falls below the standard - they are not suitable.

Neodymium magnetic rollers offer many advantages, including 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, you should cleaning regularly, avoiding temperatures up to 80°C. The rollers feature waterproofing IP67, so if they are not sealed, the magnets inside can rust and weaken. Magnetic field measurements is recommended be carried out once every 24 months. Care should be taken, as it’s possible of finger injury. 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 used in the food industry, recycling, and plastic processing, where metal separation is crucial.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They virtually do not lose power, because even after 10 years, the performance loss is only ~1% (in laboratory conditions),
They remain magnetized despite exposure to magnetic noise,
The use of a mirror-like nickel surface provides a smooth finish,
The outer field strength of the magnet shows elevated magnetic properties,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
With the option for fine forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
Significant impact in advanced technical fields – they serve a purpose in hard drives, electric drives, medical equipment as well as high-tech tools,
Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,

Disadvantages of rare earth magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to mechanical hits, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture while also reinforces its overall robustness,
High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent weakening 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,
Magnets exposed to humidity can corrode. Therefore, for outdoor applications, we recommend waterproof types made of plastic,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is risky,
Safety concern linked to microscopic shards may arise, when consumed by mistake, which is important in the protection of children. Moreover, tiny components from these assemblies might hinder health screening if inside the body,
Due to the price of neodymium, their cost is above average,

Caution with Neodymium Magnets

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

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

Neodymium magnets can demagnetize at high temperatures.

Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

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

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Strong 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. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets are not recommended for 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. 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 incredibly fragile, they easily crack and can become damaged.

Neodymium magnets are fragile and will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

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

Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.

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

If you have a nickel allergy, avoid contact with neodymium magnets.

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