The device roller magnetic is based on 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 elements from other materials. An important element of its operation is the 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 range and strength of the separator's operation.

Generally speaking, magnetic separators are used to extract ferromagnetic particles. If the cans are made of ferromagnetic materials, the separator will effectively segregate them. However, if the cans are made of non-ferromagnetic materials, such as aluminum, the magnetic separator will not be effective.

Yes, magnetic rollers are employed in the food industry to clear metallic contaminants, such as iron fragments or iron dust. Our rollers are built from durable acid-resistant steel, EN 1.4301, suitable for contact with food.

Magnetic rollers, often called cylindrical magnets, are used in metal separation, food production as well as recycling. They help in extracting iron dust during the process of separating metals from other materials.

Our magnetic rollers are composed of a neodymium magnet anchored in a stainless steel tube cylinder made 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 forces, 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.

Usually it is believed that the stronger the magnet, the more effective. But, 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 application and expected needs. The standard operating temperature of a magnetic bar is 80°C.

If the magnet is more flat, the magnetic force lines will be short. Otherwise, in the case of a thicker magnet, the force lines are extended and reach further.

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

In a salt water environment, AISI 316 steel is recommended due to its excellent 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 devices that may utilize complex 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 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 result 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 rollers 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.

To properly maintain of neodymium magnetic rollers, it is recommended cleaning regularly, 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 every two years. 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.

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 as well as disadvantages of neodymium magnets NdFeB.

Apart from immense strength, neodymium magnets have the following advantages:

They do not lose their strength (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
They are highly resistant to demagnetization by external magnetic sources,
In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
They have very 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...
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 modern technologies – find application in computer drives, electric motors, medical equipment or very modern machines.

Disadvantages of neodymium magnets:

They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. 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 loss in strength (although it is worth noting that this is dependent on the shape 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. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Health risk to health from tiny fragments of magnets are risky, in case of ingestion, which is particularly important in the context of children's health. It's also worth noting that miniscule components of these magnets can complicate diagnosis in case of swallowing.

Safety Precautions

Neodymium magnets can demagnetize at high temperatures.

Even though magnets have been found 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.

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Keep neodymium magnets away from TV, wallet, and computer HDD.

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

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they 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.

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. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

The magnet coating contains nickel, so be cautious 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.

Dust and powder from neodymium magnets are highly 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.

Magnets made of neodymium are characterized by their fragility, which can cause them to crumble.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as 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.

Neodymium magnets are the most powerful magnets ever invented. Their power can shock you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

If the joining of neodymium magnets is not under control, then they may crumble and also crack. You can't approach them to each other. At a distance less than 10 cm you should hold them extremely strongly.
