The main task of the filter is catching iron filings from flour, sugar, granules, or regrind. Essential in the food industry to meet HACCP standards and ensure product purity. They secure machine screws and molds from destruction by bolts, nuts, or wires.
For basic protection against so-called "tramp iron" (coarse iron), the standard model is sufficient. 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.
Filings should be wiped off with a cloth, glove, or blown off with compressed air after removing the grate from the installation. In versions with cover tubes (Easy Clean system), just slide out the magnetic inserts, and the filings will fall off by themselves. Regular cleaning is key to maintaining separator efficiency and throughput.
We fulfill orders for round, square, and rectangular separators according to customer specifications. 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. We help in meeting quality and audit standards in production plants.

Advantages and disadvantages of Nd2Fe14B magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:
  • Their power is maintained, and after approximately 10 years it decreases only by ~1% (theoretically),
  • Magnets effectively resist against demagnetization caused by foreign field sources,
  • Thanks to the smooth finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
  • Magnets are distinguished by very high magnetic induction on the working surface,
  • 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 ability of flexible forming and customization to individualized solutions, NdFeB magnets can be produced in a broad palette of shapes and sizes, which expands the range of possible applications,
  • Wide application in future technologies – they are utilized in HDD drives, brushless drives, medical devices, also industrial machines.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets lose their power 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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • Due to limitations in producing threads and complex shapes in magnets, we propose using cover - magnetic holder.
  • Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Detachment force of the magnet in optimal conditionswhat it depends on?

The specified lifting capacity concerns the peak performance, obtained under optimal environment, meaning:
  • using a plate made of mild steel, acting as a circuit closing element
  • possessing a thickness of min. 10 mm to ensure full flux closure
  • characterized by lack of roughness
  • without the slightest air gap between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at ambient temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

In real-world applications, the actual lifting capacity results from a number of factors, presented from the most important:
  • Distance – the presence of any layer (rust, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
  • Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, 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 load capacity.

Safety rules for work with NdFeB magnets
Keep away from electronics

A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.

Allergic reactions

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.

Safe distance

Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).

Keep away from children

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.

Bone fractures

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

ICD Warning

Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.

Fire warning

Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.

Eye protection

Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them cracking into small pieces.

Do not underestimate power

Handle magnets consciously. Their immense force can surprise even professionals. Plan your moves and do not underestimate their force.

Thermal limits

Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
