The device rod magnetic is based on the use of neodymium magnets, which are placed in a construction made of stainless steel mostly AISI304. In this way, it is possible to efficiently separate ferromagnetic particles from the mixture. A fundamental component of its operation is the use of repulsion of N and S poles of neodymium magnets, which enables magnetic substances to be attracted. The thickness of the embedded magnet and its structure pitch determine the power and range of the separator's operation.

Generally speaking, magnetic separators are designed to separate ferromagnetic elements. If the cans are ferromagnetic, 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 effectively segregate them.

Yes, magnetic rollers are employed in the food industry for the elimination of metallic contaminants, including iron fragments or iron dust. Our rods are built from acid-resistant steel, EN 1.4301, suitable for contact with food.

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

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 will be with M8 threaded openings, allowing for quick installation in machines or magnetic filter drawers. A "blind" version is also possible in manual separators.

In terms of forces, 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.

Usually it is believed that the greater the magnet's power, the more efficient it is. Nevertheless, 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 specific 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 more compressed. Otherwise, when the magnet is thick, the force lines will be longer and reach further.

For creating the casings of magnetic separators - rollers, frequently 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 stand out for their specific arrangement of poles and their capability to attract magnetic particles directly onto their surface, in contrast to other separators that often use complex filtration systems.

Technical designations and terms related to magnetic separators comprise amongst others magnet pitch, polarity, and magnetic induction, 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, aiming to find the highest magnetic field value close to 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 falls below the standard - they are not suitable.

Neodymium magnetic rollers offer a range of benefits such as excellent separation efficiency, strong magnetic field, and durability. However, some of the downsides may involve the requirement for frequent cleaning, greater weight, and potential installation difficulties.

To properly maintain of neodymium magnetic rollers, it is advised {to clean them regularly from deposits, avoid extreme temperatures above 80 degrees, and to clean them regularly, avoiding temperatures above 80 degrees. The rollers our rollers have an IP67 waterproof rating, so if they are not sealed, the magnets inside may rust and lose their strength. Roller inspections are recommended to be conducted once every 24 months. Caution should be exercised during use as there is a risk of finger injury. If the protective tube is only 0.5 mm thick, it can be worn down, which, in turn, may lead to issues with the magnetic rod becoming unsealed and product contamination. The effective operating range of the roller equals its diameter, fi25mm is approximately 25mm active range, while fi32 is about 40mm.

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 approximately 10 years, their power decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic sources extremely well,
In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
They have very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
Key role in advanced technologically fields – are utilized in hard drives, electric drive mechanisms, medical apparatus and very 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, we recommend 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,
Magnets lose their strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Possible danger associated with microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, miniscule components of these products have the potential to hinder the diagnostic process in case of swallowing.

Handle with Care: Neodymium Magnets

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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 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.

The magnet is coated with nickel. Therefore, exercise caution 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 away 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.

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

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

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

Neodymium magnets produce strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

It is important to keep neodymium magnets out of reach from children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.

If have a finger between or alternatively on the path of attracting magnets, there may be a large cut or a fracture.

Neodymium magnetic are extremely fragile, resulting in breaking.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. 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.
