Shopping tips

A magnetic beam (plate separator) is a powerful industrial magnet in a stainless steel housing. It can also be mounted in a gravity channel down which raw material falls. Ensures high quality of the final product in plastic recycling, wood, and the food industry.
Ferrite separators are characterized by a deep, penetrating magnetic field. They are ideal for catching large pieces of iron (screws, nails, cans, excavator teeth) from a long distance. Neodymium separators have an extremely strong surface field, but shallower (shorter range). The choice depends on the size of contaminants and the thickness of the raw material layer on the belt.
The construction is tightly welded from acid-resistant sheet, which guarantees tightness. This guarantees hygiene and ease of cleaning, which is crucial in the food industry. Suitable for chemical, food, and pharmaceutical industries.
It is a device operated manually by an operator. Scrap is removed by mechanically moving it to the edge, where the magnetic field is weaker. Optionally, we offer systems facilitating cleaning (Extra Clean), which speed up maintenance.
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 and disadvantages of NdFeB magnets.

In addition to their long-term stability, neodymium magnets provide the following advantages:

  • They do not lose power, even during approximately ten years – the reduction in strength is only ~1% (according to tests),
  • Magnets very well defend themselves against demagnetization caused by external fields,
  • A magnet with a shiny silver surface has an effective appearance,
  • The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to modularity in designing and the capacity to adapt to individual projects,
  • Universal use in modern industrial fields – they are utilized in hard drives, brushless drives, medical equipment, and industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions

Disadvantages of neodymium magnets:

  • At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • Limited ability of making nuts in the magnet and complicated forms - preferred is a housing - magnetic holder.
  • Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical after entering the body.
  • With large orders the cost of neodymium magnets is a challenge,

Maximum lifting force for a neodymium magnet – what it depends on?

Holding force of 0 kg is a result of laboratory testing executed under specific, ideal conditions:

  • on a plate made of structural steel, optimally conducting the magnetic flux
  • possessing a thickness of min. 10 mm to avoid saturation
  • with a surface cleaned and smooth
  • without the slightest air gap between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Bear in mind that the application force will differ influenced by the following factors, in order of importance:

  • Distance (betwixt the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Steel thickness – insufficiently thick sheet does not close the flux, causing part of the power to be lost to the other side.
  • Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
  • Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
  • Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

* Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance {between} the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets

Keep away from electronics

Be aware: rare earth magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and GPS.

Do not give to children

Neodymium magnets are not intended for children. Eating a few magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.

Physical harm

Pinching hazard: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Nickel allergy

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.

Machining danger

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Heat sensitivity

Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Shattering risk

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them breaking into small pieces.

Magnetic media

Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).

Safe operation

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Implant safety

Patients with a pacemaker have to maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.

Danger!
