The device rod 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 precisely remove ferromagnetic particles from different substances. An important element of its operation is the use of repulsion of magnetic poles N and S, which enables magnetic substances to be collected. The thickness of the magnet and its structure pitch affect the range and strength of the separator's operation.

Generally speaking, magnetic separators are designed to segregate ferromagnetic particles. If the cans are made from 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 the food sector to remove metallic contaminants, for example iron fragments or iron dust. Our rods are made from acid-resistant steel, AISI 304, suitable for contact with food.

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

Our magnetic rollers are composed of neodymium magnets anchored in a stainless steel tube casing 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 simple mounting 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 and N52.

Usually it is believed that the greater the magnet's power, the better. Nevertheless, the strength 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 expected needs. The standard operating temperature of a magnetic bar is 80°C.

If the magnet is more flat, the magnetic force lines are short. On the other hand, in the case of a thicker magnet, the force lines are longer and reach further.

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

In a saltwater environment, type AISI 316 steel is highly recommended due to its outstanding anti-corrosion properties.

Magnetic rollers are characterized by their unique configuration of poles and their ability to attract magnetic substances directly onto their surface, as opposed to other devices 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 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 rollers 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 the requirement for frequent cleaning, greater weight, and potential installation difficulties.

To properly maintain of neodymium magnetic rollers, it is recommended {to clean them regularly from deposits, avoid extremal temperatures up to 80°C, and to clean them regularly, avoiding temperatures up to 80°C. The rollers our rollers have an IP67 waterproof rating, so if they are not watertight, the magnets inside may oxidize and weaken. Roller inspections are suggested to be conducted 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 can wear out, which, in turn, can result in issues with the magnetic rod becoming unsealed and product contamination. The effective operating range of the roller equals its diameter, fi25mm is approximately 25mm active range, while fi32 is about 40mm.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose power over time. 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 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 a wide range of shapes and sizes, which amplifies their universality in usage.
Key role in advanced technologically fields – find application in hard drives, electric drive mechanisms, medical devices or other modern machines.

Disadvantages of neodymium magnets:

They can break 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 at the same time 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 reduction 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,
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,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Health risk to health from tiny fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting young children. Furthermore, miniscule components of these devices are able to be problematic in medical diagnosis in case of swallowing.

Safety Precautions

Keep neodymium magnets away from 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.

Do not place neodymium magnets 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 videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

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.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, 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.

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can surprise 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.

Do not bring neodymium magnets close to GPS and smartphones.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnetic are highly delicate, they easily crack and can become damaged.

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.

The magnet coating is made of nickel, so be cautious if you have an 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.

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 is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

If you have a finger between or alternatively on the path of attracting magnets, there may be a large cut or even a fracture.
