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 efficiently separate ferromagnetic particles from other materials. A key aspect of its operation is the use of repulsion of magnetic poles N and S, which causes magnetic substances to be attracted. The thickness of the magnet and its structure 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, 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 the food industry for the elimination of metallic contaminants, for example iron fragments or iron dust. Our rods are made from acid-resistant steel, AISI 304, intended for use in food.

Magnetic rollers, otherwise magnetic separators, find application in food production, metal separation as well as recycling. They help in extracting iron dust during the process of separating metals from other materials.

Our magnetic rollers are built with a neodymium magnet placed in a tube made of stainless steel with a wall thickness of 1mm.

From both sides of the magnetic bar can be with M8 threaded holes - 18 mm, enabling 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 magnetic force lines, flux density 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 more efficient it is. However, the effectiveness 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 application and anticipated needs. The standard operating temperature of a magnetic bar is 80°C.

If the magnet is more flat, the magnetic force lines are short. By contrast, when the magnet is thick, the force lines are longer and extend over a greater distance.

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

In a salt water environment, AISI 316 steel is recommended thanks to its outstanding corrosion resistance.

Magnetic rollers stand out for their specific arrangement of poles and their ability to attract magnetic particles directly onto their surface, in contrast to other devices that often use more complicated filtration systems.

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

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 outcome is checked in a value table - the lowest is N30. All designations below N27 or N25 suggest 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. Disadvantages may include the need for regular cleaning, higher cost, and potential installation challenges.

To properly maintain of neodymium magnetic rollers, you should regularly cleaning them from contaminants, avoiding high temperatures above 80 degrees, 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. Magnetic field measurements is recommended 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 lead to 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.

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.

Apart from their strong magnetism, neodymium magnets have these key benefits:

They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
They are very resistant to demagnetization caused by external magnetic fields,
In other words, due to the glossy nickel coating, the magnet obtains an professional appearance,
They possess intense magnetic force measurable at the magnet’s surface,
Thanks to their high temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
The ability for precise shaping or adaptation to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
Significant impact in cutting-edge sectors – they are utilized in data storage devices, rotating machines, medical equipment as well as other advanced devices,
Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of neodymium magnets:

They can break when subjected to a heavy impact. If the magnets are exposed to shocks, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage and enhances its overall robustness,
They lose field intensity at increased temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a damp environment. If exposed to rain, we recommend using waterproof magnets, such as those made of plastic,
The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is restricted,
Potential hazard linked to microscopic shards may arise, if ingested accidentally, which is significant in the context of child safety. Moreover, small elements from these assemblies might interfere with diagnostics once in the system,
In cases of mass production, neodymium magnet cost may not be economically viable,

Detachment force of the magnet in optimal conditions – what contributes to it?

The given pulling force of the magnet represents the maximum force, assessed in ideal conditions, that is:

with mild steel, used as a magnetic flux conductor
of a thickness of at least 10 mm
with a refined outer layer
with no separation
with vertical force applied
in normal thermal conditions

Determinants of practical lifting force of a magnet

In practice, the holding capacity of a magnet is conditioned by these factors, from crucial to less important:

Air gap between the magnet and the plate, since even a very small distance (e.g. 0.5 mm) can cause a drop in lifting force of up to 50%.
Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.

* Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance {between} the magnet’s surface and the plate reduces the load capacity.

Handle Neodymium Magnets Carefully

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

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, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

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.

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a significant injury may occur. Magnets, depending on their size, can even cut off a finger or alternatively there can be a serious pressure or a fracture.

Neodymium magnets are not recommended for people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.

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.

Do not give neodymium magnets to children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Neodymium magnets can become demagnetized at high temperatures.

Despite the fact that 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.

Avoid contact with neodymium magnets 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are the most powerful magnets ever invented. Their strength 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.

Neodymium magnetic are highly susceptible to damage, resulting in breaking.

Neodymium magnetic are fragile as well as 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.
