The magnetic separator, namely the magnetic roller, uses the power of neodymium magnets, which are placed in a construction made of stainless steel usually AISI304. In this way, it is possible to efficiently separate ferromagnetic elements from the mixture. A fundamental component of its operation is the repulsion of magnetic poles N and S, which allows magnetic substances to be attracted. The thickness of the magnet and its structure's pitch affect the range and strength of the separator's operation.

Generally speaking, magnetic separators serve to separate ferromagnetic particles. If the cans are ferromagnetic, a magnetic separator will be effective. 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, including iron fragments or iron dust. Our rollers are made from acid-resistant steel, EN 1.4301, intended for contact with food.

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

Our magnetic rollers consist of a neodymium magnet embedded in a tube of stainless steel with a wall thickness of 1mm.

From both sides of the magnetic bar can be with M8 threaded openings, which enables easy installation in machines or magnetic filter drawers. A "blind" version is also possible in manual separators.

In terms of magnetic properties, 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 as well as N52.

Generally it is believed that the stronger the magnet, the more efficient it is. However, the value of the magnet's power is based 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. By contrast, in the case of a thicker magnet, the force lines are longer and extend over a greater distance.

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

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

Magnetic bars 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 may utilize complex filtration systems.

Technical designations and terms related to magnetic separators include amongst others magnet pitch, polarity, and magnetic induction, as well as the type of steel used.

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 result is verified in a value table - the lowest is N30. All designations below N27 or N25 indicate recycling that doesn't meet the standard - they are not suitable.

Neodymium magnetic bars offer many advantages, including a very strong magnetic field, the ability to capture even the tiniest metal particles, 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, you should they should be regularly cleaned, avoiding temperatures above 80 degrees. The rollers our rollers have waterproofing IP67, so if they are leaky, the magnets inside can rust and lose their power. Testing of the rollers is recommended be carried out once every 24 months. Care should be taken, 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 corresponds 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, used for separating ferromagnetic contaminants from raw 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.

In addition to immense power, neodymium magnets have the following advantages:

They do not lose strength over time. After about 10 years, their power decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic sources extremely well,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They exhibit very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by very 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 enhances their versatility in applications.
Significant importance in the industry of new technologies – are utilized in HDD drives, electric motors, medical devices or other modern machines.

Disadvantages of neodymium magnets:

They are prone to breaking as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested 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,
High temperatures can reduce the strength 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,
They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Potential hazard associated with microscopic parts of magnets are risky, in case of ingestion, which is crucial in the aspect of protecting young children. Furthermore, tiny parts of these magnets are able to complicate diagnosis after entering the body.

Handle with Care: Neodymium Magnets

Keep neodymium magnets as far away as possible from GPS and smartphones.

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.

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 happens because such devices have a function to deactivate them in a magnetic field.

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 attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.

Neodymium magnets are the most powerful magnets ever created, and their strength can surprise you.

To use 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.

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.

Dust and powder from neodymium magnets are highly 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.

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

Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

The magnet coating contains nickel, so be cautious if you have a nickel 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are characterized by their fragility, which can cause them to shatter.

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.

Do not give neodymium magnets to children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.
