Shopping tips

Magnetic grates serve for precise separation of metal contaminants from bulk raw materials. Essential in the food industry to meet HACCP standards and ensure product purity. 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.
Operation requires periodic removal of the grate and cleaning the rods of stuck metal. Since the magnets are very strong, filings stick firmly - you can use adhesive tape to remove them (tape method). Regular cleaning is key to maintaining separator efficiency and throughput.
Yes, we are a manufacturer and make grates to any size and shape. We design multi-level separators for specific machines and capacities. We ensure short lead times and European quality of execution from acid-resistant steel.
Our separators are made of acid-resistant steel AISI 304 or 316L, which permits them for contact with food. Welds are ground and polished smooth, which prevents accumulation of bacteria and product. These products are commonly used in HACCP, IFS, and BRC systems.

Pros and cons of neodymium magnets.

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

  • They retain full power for almost ten years – the loss is just ~1% (in theory),
  • They are extremely resistant to demagnetization induced by external disturbances,
  • Thanks to the shiny finish, the coating of nickel, gold-plated, or silver-plated gives an professional appearance,
  • Magnetic induction on the surface of the magnet is impressive,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Considering the option of accurate molding and adaptation to specialized solutions, NdFeB magnets can be produced in a broad palette of shapes and sizes, which makes them more universal,
  • Huge importance in modern technologies – they are commonly used in data components, electric drive systems, medical devices, and multitasking production systems.
  • Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Disadvantages of neodymium magnets:

  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Limited possibility of producing threads in the magnet and complex forms - preferred is a housing - magnet mounting.
  • Possible danger resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products can disrupt the diagnostic process medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Maximum magnetic pulling forcewhat contributes to it?

The declared magnet strength refers to the maximum value, obtained under laboratory conditions, specifically:

  • using a base made of low-carbon steel, serving as a ideal flux conductor
  • whose thickness is min. 10 mm
  • with a plane perfectly flat
  • without the slightest clearance between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at temperature room level

Key elements affecting lifting force

Real force impacted by specific conditions, including (from most important):

  • Air gap (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, rust or dirt).
  • Force direction – 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.
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
  • Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

* Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance {between} the magnet and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Protective goggles

Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.

Operating temperature

Do not overheat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Protect data

Data protection: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).

Handling rules

Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can move away.

Keep away from electronics

Remember: rare earth magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.

Do not give to children

Always keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.

Bodily injuries

Big blocks can crush fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Do not drill into magnets

Powder produced during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Health Danger

People with a pacemaker should keep an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
