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. 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. We recommend them for protecting machines against large, heavy scrap (so-called tramp iron). Neodymium separators have an extremely strong surface field, but shallower (shorter range). The decision should be made based on the type of separated material and cleanliness requirements.
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. 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.

Strengths and weaknesses of rare earth magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • Their magnetic field remains stable, and after around ten years it decreases only by ~1% (theoretically),
  • They do not lose their magnetic properties even under external field action,
  • By using a decorative layer of gold, the element gains an aesthetic look,
  • Magnets are characterized by exceptionally strong magnetic induction on the surface,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Considering the ability of free forming and adaptation to specialized solutions, neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of possible applications,
  • Huge importance in modern industrial fields – they are commonly used in mass storage devices, electromotive mechanisms, medical equipment, and industrial machines.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Cons

Drawbacks and weaknesses of neodymium magnets: tips and applications.
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • Heat sensitivity: observe the temperature specified for this product. Overheating may permanently weaken the magnet.
  • Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable 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.
  • Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what affects it?

Holding force of 0.00 kg is a measurement result executed under specific, ideal conditions:
  • on a block made of structural steel, effectively closing the magnetic field
  • whose thickness equals approx. 10 mm
  • characterized by even structure
  • with direct contact (without coatings)
  • for force acting at a right angle (in the magnet axis)
  • in neutral thermal conditions

Determinants of lifting force in real conditions

Holding efficiency impacted by working environment parameters, such as (from priority):
  • Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Plate material – mild steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
  • Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
  • Temperature – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.

Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.

Safety rules for work with neodymium magnets
Life threat

Individuals with a pacemaker should keep an safe separation from magnets. The magnetic field can stop the functioning of the implant.

Magnet fragility

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them cracking into small pieces.

Operating 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.

Threat to electronics

Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Respect the power

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

Do not drill into magnets

Powder created during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.

GPS and phone interference

A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.

Danger to the youngest

Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of children and animals.

Sensitization to coating

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, cease handling magnets and use protective gear.

Serious injuries

Protect your hands. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
