SM 32x500 [2xM8] / N52 - magnetic separator

1 562.10 ZŁ / pcs

The main mechanism of the magnetic separator is the use of neodymium magnets, which are embedded in a construction made of stainless steel usually AISI304. In this way, it is possible to effectively separate ferromagnetic particles from other materials. A key aspect of its operation is the use of repulsion of N and S poles of neodymium magnets, which causes magnetic substances to be targeted. 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 separate ferromagnetic elements. If the cans are made from ferromagnetic materials, 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 find application in the food industry to clear metallic contaminants, such as iron fragments or iron dust. Our rods are constructed from durable acid-resistant steel, EN 1.4301, approved for contact with food.

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

Our magnetic rollers are composed of 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 can be with M8 threaded holes - 18 mm, allowing for quick installation in machines or magnetic filter drawers. A "blind" version is also possible in manual separators.

In terms of features, 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 two materials, N42 as well as N52.

Usually 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 anticipated needs. The standard operating temperature of a magnetic bar is 80°C.

When the magnet is more flat, the magnetic force lines are short. On the other hand, when the magnet is thick, the force lines are extended and reach further.

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

In a salt water environment, AISI 316 steel is recommended thanks to its excellent anti-corrosion properties.

Magnetic rollers are characterized by their unique configuration of poles and their ability to attract magnetic particles directly onto their surface, in contrast to other devices that may utilize complex filtration systems.

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

Magnetic induction for a magnet on a roller is determined using a teslameter or a gaussmeter with a flat Hall-effect probe, seeking the highest magnetic field value near the magnetic pole. The result is checked in a value table - the lowest is N30. All designations less than N27 or N25 suggest recycling that doesn't meet the standard - they are not suitable.

Neodymium magnetic bars offer a range of benefits such as excellent separation efficiency, strong magnetic field, and durability. Disadvantages may include higher cost compared to other types of magnets and the need for regular maintenance.

To properly maintain of neodymium magnetic rollers, it’s worth cleaning after each use, avoiding temperatures above 80 degrees. The rollers feature waterproofing IP67, so if they are leaky, the magnets inside can oxidize and weaken. Testing of the rollers should be carried out every two years. Care should be taken, as there is a risk getting pinched. If the protective tube is only 0.5 mm thick, it may wear out, which in turn could cause problems with the magnetic rod seal and product contamination. The 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.

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 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 their notable magnetism, neodymium magnets have these key benefits:

They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
Their ability to resist magnetic interference from external fields is notable,
By applying a bright layer of nickel, the element gains a sleek look,
They possess strong magnetic force measurable at the magnet’s surface,
These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to profile),
The ability for precise shaping or adjustment to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
Key role in cutting-edge sectors – they are utilized in HDDs, electromechanical systems, diagnostic apparatus as well as other advanced devices,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of rare earth magnets:

They are fragile when subjected to a powerful impact. If the magnets are exposed to physical collisions, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time strengthens its overall strength,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a damp environment – during outdoor use, we recommend using encapsulated magnets, such as those made of polymer,
The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is not feasible,
Safety concern related to magnet particles may arise, if ingested accidentally, which is significant in the protection of children. Furthermore, tiny components from these magnets may complicate medical imaging if inside the body,
In cases of mass production, neodymium magnet cost is a challenge,

Be Cautious with Neodymium Magnets

Neodymium magnetic are extremely fragile, leading to their cracking.

Neodymium magnetic are delicate and will shatter if allowed to collide with each other, even from a distance of a few centimeters. 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.

Do not give neodymium magnets to children.

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 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.

Never bring neodymium magnets close to a phone and GPS.

Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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

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

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 swellings.

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

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.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

People with pacemakers are advised to avoid neodymium magnets.

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.
