These separators are installed to clean the product from unwanted ferromagnetic metals. They are also used in recycling, ceramics, and the chemical industry. They protect machines from failure and ensure high quality of the final product.
The Standard version (approx. 6000-8000 Gauss) effectively catches screws, nails, washers, and larger filings. The High Power version (12000-14000 Gauss) is intended for capturing very fine magnetic dust. In the food industry, the strongest version (10kGs+) is often required.
Filings should be wiped off with a cloth, glove, or blown off with compressed air after removing the grate from the installation. Since the magnets are very strong, filings stick firmly - you can use adhesive tape to remove them (tape method). We recommend frequent checks of the filter's contamination status, e.g., once per work shift.
We fulfill orders for round, square, and rectangular separators according to customer specifications. We also make entire drawer modules in housings (so-called housings). We ensure short lead times and European quality of execution from acid-resistant steel.
The material of execution complies with rigorous requirements of the food and pharmaceutical industries. Welds are ground and polished smooth, which prevents accumulation of bacteria and product. We help in meeting quality and audit standards in production plants.

Strengths and weaknesses of rare earth magnets.

Pros

Besides their durability, neodymium magnets are valued for these benefits:
  • They do not lose power, even during nearly 10 years – the decrease in lifting capacity is only ~1% (theoretically),
  • Neodymium magnets prove to be extremely resistant to demagnetization caused by external magnetic fields,
  • By applying a lustrous coating of gold, the element presents an aesthetic look,
  • Magnetic induction on the working layer of the magnet turns out to be exceptional,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Due to the potential of precise forming and adaptation to custom solutions, magnetic components can be manufactured in a broad palette of forms and dimensions, which increases their versatility,
  • Universal use in future technologies – they are commonly used in HDD drives, brushless drives, diagnostic systems, also modern systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of producing nuts in the magnet and complex shapes - preferred is a housing - mounting mechanism.
  • Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum holding power of the magnet – what affects it?

The declared magnet strength represents the limit force, recorded under ideal test conditions, meaning:
  • on a block made of structural steel, effectively closing the magnetic flux
  • whose transverse dimension is min. 10 mm
  • characterized by lack of roughness
  • under conditions of ideal adhesion (surface-to-surface)
  • during pulling in a direction perpendicular to the plane
  • at standard ambient temperature

Magnet lifting force in use – key factors

In practice, the actual holding force is determined by several key aspects, ranked from the most important:
  • Air gap (between the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or debris).
  • Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
  • Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
  • Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
  • Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Safe handling of NdFeB magnets
Respect the power

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can react.

Dust explosion hazard

Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Keep away from computers

Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.

Operating temperature

Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.

Magnets are brittle

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them breaking into small pieces.

Phone sensors

A powerful magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets near a device to prevent breaking the sensors.

ICD Warning

For implant holders: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.

Swallowing risk

Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Keep away from children and animals.

Nickel coating and allergies

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.

Finger safety

Pinching hazard: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
