Shopping tips

Magnetic grates serve for precise separation of metal contaminants from bulk raw materials. 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. Power of 12000 Gs allows for separation of weakly magnetic steel and work-hardened material, which is key in the food industry. To meet rigorous quality standards, we recommend the highest available induction.
Cleaning involves manually removing collected contaminants from the surface of magnetic rods. Metal holds strongly, so packing tape can be helpful, which we stick to the roller and tear off together with the filings. Regular cleaning is key to maintaining separator efficiency and throughput.
We can produce a sieve perfectly matched to your hopper or pipeline. We design multi-level separators for specific machines and capacities. 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. Smooth, polished surface ensures hygiene of the production process. We help in meeting quality and audit standards in production plants.

Strengths and weaknesses of rare earth magnets.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

  • They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
  • They do not lose their magnetic properties even under close interference source,
  • The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
  • Thanks to flexibility in forming and the capacity to customize to complex applications,
  • Wide application in future technologies – they serve a role in data components, electric motors, medical devices, also other advanced devices.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages of neodymium magnets:

  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • 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, when using outdoors
  • Due to limitations in producing nuts and complex shapes in magnets, we propose using a housing - magnetic mount.
  • Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets can complicate diagnosis 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

Maximum lifting force for a neodymium magnet – what affects it?

The lifting capacity listed is a theoretical maximum value conducted under the following configuration:

  • with the application of a sheet made of special test steel, ensuring maximum field concentration
  • with a thickness minimum 10 mm
  • with an polished contact surface
  • with direct contact (no paint)
  • under vertical force vector (90-degree angle)
  • in neutral thermal conditions

Practical lifting capacity: influencing factors

Holding efficiency impacted by working environment parameters, mainly (from most important):

  • Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Pull-off angle – note that the magnet has greatest strength 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. Magnetic flux penetrates through instead of converting into lifting capacity.
  • Plate material – mild steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
  • Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
  • Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

* Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance {between} the magnet and the plate decreases the load capacity.

Warnings

Handling rules

Use magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their force.

Risk of cracking

Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Bone fractures

Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.

This is not a toy

Adult use only. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.

Cards and drives

Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, timepieces).

Precision electronics

Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Pacemakers

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Heat sensitivity

Keep cool. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Allergy Warning

Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness appears, cease working with magnets and wear gloves.

Mechanical processing

Dust produced during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
