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.

This separator is tasked with cleaning the product (coal, aggregate, recycling) from steel contaminants. It is usually mounted above the conveyor belt (so-called overbelt) or in chutes. Ensures high quality of the final product in plastic recycling, wood, and the food industry.
Ferrite separators are characterized by a deep, penetrating magnetic field. We recommend them for protecting machines against large, heavy scrap (so-called tramp iron). Neodymium versions are used for precise cleaning of raw material from small particles (food industry, plastics). The choice depends on the size of contaminants and the thickness of the raw material layer on the belt.
The construction is tightly welded from acid-resistant sheet, which guarantees tightness. This ensures full resistance to corrosion, water, and difficult weather conditions. Suitable for chemical, food, and pharmaceutical industries.
Removing contaminants is simple but requires periodic stopping of the process or access to the magnet. Scrap is removed by mechanically moving it to the edge, where the magnetic field is weaker. To facilitate, a cleaning overlay (dump drawer) can be used, which we offer as an option.
Yes, we are a manufacturer and make plate separators to any size. We design separators according to the orderer's requirements, taking into account material specifics. Send us dimensions of your conveyor belt and type of raw material, and we will select the appropriate solution.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Pros

Besides their exceptional pulling force, neodymium magnets offer the following advantages:
  • They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
  • They are extremely resistant to demagnetization induced by external field influence,
  • In other words, due to the reflective finish of gold, the element becomes visually attractive,
  • Magnets exhibit very high magnetic induction on the working surface,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to versatility in forming and the ability to adapt to complex applications,
  • Huge importance in future technologies – they find application in hard drives, drive modules, precision medical tools, and complex engineering applications.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:
  • They are fragile upon heavy impacts. To avoid cracks, it is worth protecting 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.
  • Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
  • Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum holding power of the magnet – what affects it?

Magnet power is the result of a measurement for the most favorable conditions, taking into account:
  • on a block made of structural steel, optimally conducting the magnetic field
  • possessing a thickness of min. 10 mm to avoid saturation
  • with an polished contact surface
  • with total lack of distance (without impurities)
  • for force applied at a right angle (in the magnet axis)
  • in neutral thermal conditions

Practical lifting capacity: influencing factors

Bear in mind that the application force may be lower influenced by elements below, starting with the most relevant:
  • Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Direction of force – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
  • Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
  • Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
  • Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Warnings
Magnet fragility

NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them shattering into shards.

Nickel coating and allergies

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.

Warning for heart patients

People with a ICD have to maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Threat to navigation

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.

Fire risk

Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Finger safety

Big blocks can smash fingers in a fraction of a second. Never place your hand between two strong magnets.

Conscious usage

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Electronic hazard

Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Product not for children

Absolutely keep magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.

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.
