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.

It is a device used to catch unwanted metals from bulk raw materials transported on a belt. It can also be mounted in a gravity channel down which raw material falls. The main goal is to protect crushing machines from destruction and ensure product purity.
Ferrite is cheaper and has deeper field penetration, which is good with a thick layer of raw material. They work well in initial separation in recycling and mining. 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 separator housing is high-quality stainless steel, welded by TIG method. Thanks to this, the device is waterproof, dustproof, and very durable. The product meets standards for the food industry (HACCP/IFS/BRC).
It is a device operated manually by an operator. 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.
As a manufacturer, we fulfill individual orders for specific conveyor belt widths. 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.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Pros

Apart from their superior power, neodymium magnets have these key benefits:
  • They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
  • They are resistant to demagnetization induced by external disturbances,
  • By covering with a decorative layer of nickel, the element acquires an professional look,
  • Neodymium magnets ensure maximum magnetic induction on a contact point, which allows for strong attraction,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
  • Thanks to the option of flexible molding and customization to custom needs, magnetic components can be manufactured in a variety of forms and dimensions, which makes them more universal,
  • Significant place in high-tech industry – they are utilized in magnetic memories, motor assemblies, diagnostic systems, and technologically advanced constructions.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Disadvantages

Cons of neodymium magnets and ways of using them
  • To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
  • 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 recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic mount.
  • Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

The force parameter is a measurement result performed under specific, ideal conditions:
  • using a sheet made of mild steel, acting as a ideal flux conductor
  • possessing a massiveness of at least 10 mm to ensure full flux closure
  • with an ideally smooth contact surface
  • with total lack of distance (no coatings)
  • under vertical application of breakaway force (90-degree angle)
  • at standard ambient temperature

Practical aspects of lifting capacity – factors

In real-world applications, the real power results from several key aspects, presented from most significant:
  • Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets
Medical implants

Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to work with the magnets.

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.

Powerful field

Handle with care. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can react.

Keep away from computers

Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

Nickel allergy

Some people have a sensitization to nickel, which is the standard coating for NdFeB magnets. Frequent touching can result in an allergic reaction. We strongly advise wear protective gloves.

Finger safety

Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Machining danger

Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

GPS Danger

Note: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.

Do not give to children

NdFeB magnets are not suitable for play. Eating a few magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.

Magnets are brittle

Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
