The device roller magnetic is based on the use of neodymium magnets, which are welded in a casing made of stainless steel usually AISI304. As a result, it is possible to effectively separate ferromagnetic elements from different substances. An important element of its operation is the repulsion of magnetic poles N and S, which allows magnetic substances to be attracted. The thickness of the embedded magnet and its structure pitch affect the power and range of the separator's operation.

Generally speaking, magnetic separators are used to segregate 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 effectively segregate them.

Yes, magnetic rollers find application in the food industry to remove metallic contaminants, for example iron fragments or iron dust. Our rollers are made from acid-resistant steel, EN 1.4301, approved for contact with food.

Magnetic rollers, often called cylindrical magnets, are employed 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 composed of neodymium magnets anchored in a stainless steel tube casing of stainless steel with a wall thickness of 1mm.

Both ends of the magnetic bar can 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 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.

Often it is believed that the greater the magnet's power, the better. Nevertheless, 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 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 short. Otherwise, in the case of a thicker magnet, the force lines are longer and extend over a greater distance.

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

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

Magnetic rollers are characterized by their specific arrangement of poles and their capability 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 comprise among others polarity, magnetic induction, magnet pitch, as well as the steel type applied.

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 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 a very strong magnetic field, the ability to capture even the tiniest metal particles, and durability. However, some of the downsides may involve the requirement for frequent cleaning, greater weight, and potential installation difficulties.

For proper maintenance of neodymium magnetic rollers, it is suggested {to clean them regularly from deposits, avoid extremal temperatures above 80 degrees, and to clean them regularly, avoiding temperatures up to 80°C. The rollers have an IP67 waterproof rating, so if they are not sealed, the magnets inside may rust and lose their strength. Magnetic field measurements are recommended to be conducted every two years. 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 wear out, which, in turn, may lead to issues with the magnetic rod becoming unsealed and product contamination. The Roller operating range 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 power, neodymium magnets have the following advantages:

They do not lose strength over time - after 10 years, their strength decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field very well,
In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
They exhibit extremely 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 or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
Wide application in the industry of new technologies – are utilized in computer drives, electric drive mechanisms, medical apparatus and very modern machines.

Disadvantages of neodymium magnets:

They can break as they are 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 simultaneously increases its overall strength,
They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
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 to health from tiny fragments of magnets are risky, if swallowed, which becomes significant in the aspect of protecting young children. It's also worth noting that small elements of these products can complicate diagnosis after entering the body.

Exercise Caution with Neodymium Magnets

Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can surprise you.

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

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

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

Keep neodymium magnets away from 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.

Avoid bringing neodymium magnets close to a phone or GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

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

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.

Magnets made of neodymium are highly susceptible to damage, 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 collision between the magnets, small metal fragments can be dispersed in different directions.

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 can demagnetize at high temperatures.

Despite the fact that 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.

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

Strong magnetic fields emitted by neodymium magnets can damage 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.

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

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.

Please read the article - What danger lies in neodymium magnets? You will learn how to handle them properly.
