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 can also be mounted in a gravity channel down which raw material falls. Protects mills, crushers, and shredders from falling screws, excavator teeth, or hammers.
Ferrite separators are characterized by a deep, penetrating magnetic field. They are ideal for catching large pieces of iron (screws, nails, cans, excavator teeth) from a long distance. Neodymium versions are used for precise cleaning of raw material from small particles (food industry, plastics). The decision should be made based on the type of separated material and cleanliness requirements.
The construction is tightly welded from acid-resistant sheet, which guarantees tightness. Thanks to this, the device is waterproof, dustproof, and very durable. Suitable for chemical, food, and pharmaceutical industries.
Cleaning a plate separator (static) is done manually. Just drop attracted elements (screws, wires) outside the conveyor belt area. Optionally, we offer systems facilitating cleaning (Extra Clean), which speed up maintenance.
We can produce a magnetic block perfectly matched to your installation and requirements. Dimensions and mounting system are agreed with the client at the design stage. Contact us to receive a free quote and technical drawing.

Pros and cons of neodymium magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:
  • Their power is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
  • They possess excellent resistance to magnetic field loss due to external fields,
  • The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to look better,
  • They are known for high magnetic induction at the operating surface, making them more effective,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • In view of the possibility of accurate shaping and customization to specialized solutions, magnetic components can be produced in a broad palette of forms and dimensions, which increases their versatility,
  • Fundamental importance in high-tech industry – they are commonly used in HDD drives, electric motors, precision medical tools, and technologically advanced constructions.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
  • Heat sensitivity: observe the temperature specified for this product. Overheating may permanently weaken the magnet.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • We suggest cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
  • Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting force for a neodymium magnet – what contributes to it?

Magnet power was defined for optimal configuration, taking into account:
  • using a sheet made of low-carbon steel, acting as a circuit closing element
  • whose transverse dimension equals approx. 10 mm
  • characterized by smoothness
  • without any clearance between the magnet and steel
  • under vertical force vector (90-degree angle)
  • in neutral thermal conditions

Key elements affecting lifting force

Please note that the working load may be lower subject to the following factors, starting with the most relevant:
  • Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Plate thickness – too thin plate does not accept the full field, causing part of the power to be lost to the other side.
  • Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.

Safety rules for work with neodymium magnets
Skin irritation risks

Studies show that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and choose coated magnets.

Hand protection

Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Eye protection

NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them shattering into shards.

Threat to navigation

Navigation devices and smartphones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Medical interference

Individuals with a pacemaker have to maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.

Swallowing risk

These products are not suitable for play. Eating a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.

Handling rules

Handle magnets with awareness. Their immense force can surprise even professionals. Stay alert and respect their force.

Data carriers

Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.

Power loss in heat

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.

Machining danger

Dust generated during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
