Frequently asked questions

How do I choose a separator for fine contamination and check availability?
Start with the size and type of contaminant, the material flow and the working surface. Compare the magnetic-field data and dimensions stated on the selected product card, and check current availability there.
Where can I order a separator for a production line, and what should I check?
Match the device to the installation dimensions, material flow, cleaning method and housing requirements. A drawing or the dimensions of the transfer point help determine whether a catalogue model fits or a custom version is needed.
How can I verify a separator's declared magnetic parameters before purchase?
Ask for the measured value, the point of measurement and the method or instrument used. A field-strength figure without its measurement conditions cannot be compared reliably with another product.
Can a magnetic beam withstand continuous work on a production line?
Check the construction, mounting and cleaning procedure for the chosen beam. Captured metal must be removed regularly; a layer of particles can reduce effective separation even when the magnets themselves are sound.
What roller design is suitable for a dusty environment?
Check the bearing protection, surface finish and cleaning access of the selected model. Dust accumulation and abrasion depend on the installation, so specify the actual process conditions before choosing a version.
How do I choose the size of a hand-held separator?
Match the rod diameter and length to the container and material depth, and consider the tool's weight for repeated manual work. Use the dimensions and magnetic data on the current product card.
What is a hand-held separator for, and how is it different from a built-in rod?
A built-in rod stays in the process line. A hand-held separator is moved through a material sample or container and then cleaned. It is useful for spot checks or occasional cleanup when permanent installation is not required.
Which separator type suits a small production plant?
Choose by the point in the process: a grate at a hopper, a beam over a conveyor, a built-in rod in a chute or pipe, or a hand-held tool for spot checks. A magnetic gripper handles steel parts rather than separating contamination.

A magnetic beam (plate separator) is a powerful industrial magnet in a stainless steel housing. The most common installation place is suspension over the transport belt crosswise or lengthwise. Protects mills, crushers, and shredders from falling screws, excavator teeth, or hammers.
Ferrite magnets work effectively at a greater distance (high suspension), but with less surface force. They work well in initial separation in recycling and mining. Neodymium separators have an extremely strong surface field, but shallower (shorter range). The choice depends on the size of contaminants and the thickness of the raw material layer on the belt.
We make our magnetic beams entirely of acid-resistant steel AISI 304 or 316 (on request). This guarantees hygiene and ease of cleaning, which is crucial in the food industry. It can be safely used in contact with loose food (flour, sugar, grain).
Removing contaminants is simple but requires periodic stopping of the process or access to the magnet. Just drop attracted elements (screws, wires) outside the conveyor belt area. Cleaning frequency depends on the amount of contaminants in the product - the more metal, the more often you need to clean.
Yes, we are a manufacturer and make plate separators to any size. Dimensions and mounting system are agreed with the client at the design stage. Send us dimensions of your conveyor belt and type of raw material, and we will select the appropriate solution.

Pros and cons of rare earth magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • Their power remains stable, and after approximately ten years it drops only by ~1% (according to research),
  • Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external field sources,
  • In other words, due to the shiny surface of nickel, the element gains visual value,
  • Neodymium magnets generate maximum magnetic induction on a their surface, which allows for strong attraction,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
  • Thanks to freedom in designing and the capacity to customize to unusual requirements,
  • Huge importance in modern technologies – they are utilized in data components, electromotive mechanisms, advanced medical instruments, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices

Limitations

Drawbacks and weaknesses of neodymium magnets and proposals for their use:
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
  • Heat sensitivity: observe the temperature specified for this product. Overheating may permanently weaken the magnet.
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in realizing nuts and complex forms in magnets, we propose using casing - magnetic mount.
  • Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical when they are in the body.
  • Due to complex production process, their price exceeds standard values,

Lifting parameters

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

The specified lifting capacity concerns the peak performance, recorded under optimal environment, meaning:
  • using a plate made of mild steel, functioning as a circuit closing element
  • whose transverse dimension is min. 10 mm
  • with a surface cleaned and smooth
  • with direct contact (without impurities)
  • under vertical application of breakaway force (90-degree angle)
  • at conditions approx. 20°C

Practical aspects of lifting capacity – factors

Effective lifting capacity impacted by working environment parameters, including (from most important):
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
  • Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
  • Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Precautions when working with neodymium magnets
Danger to the youngest

NdFeB magnets are not intended for children. Eating several magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.

Maximum temperature

Do not exceed the maximum operating temperature stated in the specifications of the particular product. The limit depends on the material, geometry and operating arrangement; there is no single threshold for all neodymium magnets. Overheating can permanently weaken a magnet.

Nickel coating and allergies

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, cease handling magnets and use protective gear.

Protective goggles

Neodymium magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them breaking into shards.

Magnetic interference

Be aware: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and GPS.

Life threat

People with a pacemaker should keep an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.

Cards and drives

Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.

Fire risk

Powder produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Respect the power

Exercise caution. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.

Crushing force

Big blocks can break fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
