The device roller magnetic is based on the use of neodymium magnets, which are embedded in a construction made of stainless steel mostly AISI304. As a result, it is possible to precisely remove ferromagnetic particles from different substances. 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 attracted. The thickness of the embedded magnet and its structure pitch affect the range and strength of the separator's operation.

Generally speaking, magnetic separators are designed to separate ferromagnetic elements. If the cans are made of 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 are employed in food production for the elimination of metallic contaminants, for example iron fragments or iron dust. Our rods are built from acid-resistant steel, EN 1.4301, intended for use in food.

Magnetic rollers, often called cylindrical magnets, find application in metal separation, food production as well as recycling. They help in extracting iron dust in the course of the process of separating metals from other wastes.

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

From both sides of the magnetic bar will 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 differ in terms of magnetic force lines, flux density and the field of the magnetic field. We produce them in two materials, N42 as well as N52.

Generally it is believed that the greater the magnet's power, the more effective. But, the value 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 expected needs. The standard operating temperature of a magnetic bar is 80°C.

When the magnet is thin, the magnetic force lines will be more compressed. On the other hand, in the case of a thicker magnet, the force lines are extended and extend over a greater distance.

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

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

Magnetic bars stand out for their unique configuration of poles and their ability to attract magnetic particles directly onto their surface, in contrast to other devices that often use more complicated filtration systems.

Technical designations and terms related to magnetic separators include among others magnet pitch, polarity, and magnetic induction, 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, seeking the highest magnetic field value close to the magnetic pole. The outcome is verified in a value table - the lowest is N30. All designations below N27 or N25 indicate recycling that falls below the standard - they are not suitable.

Neodymium magnetic bars offer a range of benefits such as excellent separation efficiency, strong magnetic field, and durability. However, some of the downsides may involve the need for regular cleaning, higher cost, and potential installation challenges.

For proper maintenance of neodymium magnetic rollers, it is recommended cleaning after each use, avoiding temperatures above 80 degrees. The rollers our rollers have waterproofing IP67, so if they are not sealed, the magnets inside can rust and lose their power. Testing of the rollers should be carried out once every 24 months. Caution should be taken during use, 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 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, used for separating ferromagnetic contaminants from raw materials. They are used in the food industry, recycling, and plastic processing, where the removal of iron metals and iron filings is essential.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense power, 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 are exceptionally resistant to demagnetization caused by an external magnetic field,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They exhibit extremely high magnetic induction on the surface of the magnet,
By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
Key role in advanced technologically fields – find application in computer drives, electric motors, medical apparatus and various technologically advanced devices.

Disadvantages of neodymium magnets:

They are prone to breaking as they are fragile when subjected to a powerful 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,
High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the form and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Potential hazard arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the context of children's health. Furthermore, tiny parts of these magnets have the potential to hinder the diagnostic process when they are in the body.

Handle Neodymium Magnets with Caution

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.

Magnets will crack or crumble with careless connecting to each other. You can't approach them to each other. At a distance less than 10 cm you should have them very strongly.

It is essential to maintain neodymium magnets away from youngest children.

Neodymium magnets are not toys. Do not allow children to play 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.

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. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Magnets made of neodymium are incredibly delicate, they easily crack and can crumble.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. 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.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Under no circumstances should neodymium magnets be brought close to 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.

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 should not be near 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.

Neodymium magnets can demagnetize at high temperatures.

Whilst Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

Neodymium magnets are the most powerful magnets ever created, and their power can shock 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.
