SM 32x150 [2xM8] / N42 - magnetic separator

455.10 ZŁ / pcs

The main mechanism of the magnetic separator is the use of neodymium magnets, which are placed in a construction made of stainless steel usually AISI304. In this way, it is possible to precisely remove ferromagnetic particles from different substances. A key aspect of its operation is the use of repulsion of N and S poles of neodymium magnets, which allows magnetic substances to be collected. The thickness of the magnet and its structure's pitch determine the range and strength of the separator's operation.

Generally speaking, magnetic separators serve to separate ferromagnetic particles. If the cans are ferromagnetic, the separator will effectively segregate 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 used in the food industry to clear metallic contaminants, for example iron fragments or iron dust. Our rollers are constructed from acid-resistant steel, EN 1.4301, intended for contact with food.

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

Our magnetic rollers are composed of a neodymium magnet anchored in a stainless steel tube casing made of stainless steel with a wall thickness of 1mm.

Both ends 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 forces, magnetic bars stand out in terms of flux density, magnetic force lines and the field of the magnetic field. We produce them in materials, N42 as well as N52.

Generally it is believed that the greater the magnet's power, the better. Nevertheless, the effectiveness of the magnet's power is dependent 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 more compressed. By contrast, when the magnet is thick, the force lines will be extended and extend over a greater distance.

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

In a saltwater contact, type AISI 316 steel is recommended thanks to its outstanding anti-corrosion properties.

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

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

Magnetic induction for a roller is determined 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 outcome is verified in a value table - the lowest is N30. All designations less than N27 or N25 indicate recycling that doesn't meet the standard - they are not suitable.

Neodymium magnetic bars offer a range of benefits such as a very strong magnetic field, the ability to capture even the tiniest metal particles, and durability. Disadvantages may include higher cost compared to other types of magnets and the need for regular maintenance.

For proper maintenance of neodymium magnetic rollers, you should regularly cleaning them from contaminants, avoiding extreme temperatures up to 80°C, and protecting them from moisture if the threads are not sealed – in ours, they are. The rollers our rollers have 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. 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 cause 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.

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 metal separation is crucial.

Advantages and 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 strength decreases by only ~1% (theoretically),
They are extremely resistant to demagnetization by 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,
Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes and sizes, which amplifies their universality in usage.
Key role in the industry of new technologies – are used in computer drives, electric drive mechanisms, medical equipment or very modern machines.

Disadvantages of neodymium magnets:

They are fragile when subjected to a strong 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 at the same time 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 form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
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 to health from tiny fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these magnets can be problematic in medical diagnosis when they are in the body.

Precautions

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

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

Neodymium magnets can demagnetize at high temperatures.

Even though 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.

Magnets made of neodymium are fragile as well as can easily break as well as shatter.

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. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

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.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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

The magnet is coated with nickel. Therefore, exercise caution if you have an 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 should not be in the vicinity youngest 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.

Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.

Magnets may crack or alternatively crumble with uncontrolled joining to each other. You can't move them to each other. At a distance less than 10 cm you should have them very firmly.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Magnetic 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. Avoid placing neodymium magnets in close proximity to electronic devices.
