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. It is usually mounted above the conveyor belt (so-called overbelt) or in chutes. The main goal is to protect crushing machines from destruction and ensure product purity.
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.
The separator housing is high-quality stainless steel, welded by TIG method. This guarantees hygiene and ease of cleaning, which is crucial in the food industry. The product meets standards for the food industry (HACCP/IFS/BRC).
Cleaning a plate separator (static) is done manually. Periodically wipe the working surface with a cloth or slide collected metal to the side. 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. Contact us to receive a free quote and technical drawing.

Pros as well as cons of Nd2Fe14B magnets.

Benefits

Apart from their strong magnetism, neodymium magnets have these key benefits:
  • They do not lose strength, even after nearly ten years – the decrease in lifting capacity is only ~1% (theoretically),
  • Neodymium magnets are highly resistant to magnetic field loss caused by external field sources,
  • A magnet with a shiny silver surface is more attractive,
  • They are known for high magnetic induction at the operating surface, which improves attraction properties,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • In view of the potential of flexible forming and customization to unique solutions, neodymium magnets can be produced in a variety of forms and dimensions, which increases their versatility,
  • Universal use in modern technologies – they find application in mass storage devices, brushless drives, diagnostic systems, as well as complex engineering applications.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices

Limitations

What to avoid - cons of neodymium magnets: tips and applications.
  • At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • 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 recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Limited ability of producing nuts in the magnet and complicated forms - preferred is a housing - magnetic holder.
  • Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
  • Due to complex production process, their price exceeds standard values,

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

The load parameter shown refers to the limit force, measured under optimal environment, meaning:
  • on a base made of structural steel, effectively closing the magnetic flux
  • possessing a thickness of min. 10 mm to ensure full flux closure
  • with a plane cleaned and smooth
  • without the slightest air gap between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at temperature room level

Lifting capacity in real conditions – factors

In practice, the actual holding force depends on several key aspects, presented from most significant:
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Plate material – mild steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
  • Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
  • Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed 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 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safe handling of neodymium magnets
Caution required

Exercise caution. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can move away.

Thermal limits

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.

Phone sensors

Remember: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.

Allergic reactions

A percentage of the population have a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Frequent touching can result in dermatitis. It is best to use safety gloves.

Pacemakers

People with a pacemaker have to keep an large gap from magnets. The magnetism can stop the operation of the implant.

Cards and drives

Equipment safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).

Crushing force

Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Swallowing risk

Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Keep away from kids and pets.

Machining danger

Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Protective goggles

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
