Frequently asked questions

Which rod should I choose for fine contamination?
For particles below 0.5 mm — a Ø32 mm rod in grade N52, with surface induction of about 10,000 Gs. A Ø25 rod in grade N42 gives about 6,500 Gs and is chosen for contamination above 1 mm: bolts, washers, pieces of wire.
Which rod pitch should I choose?
The narrow pitch, 40 mm centre to centre, for fine free-flowing fractions — it gives denser coverage of the cross-section. The wide pitch, 50 mm, for granulates and for damp, greasy or sticky materials, where a narrow pitch risks the material bridging above the rods.
Why does efficiency drop after a few weeks of operation?
Almost always because the separator has not been cleaned. The layer of captured particles shields the field, and further particles settle on that layer rather than on the rod surface, where the gradient is far stronger. The magnets themselves do not weaken at that rate.

The main task of the filter is catching iron filings from flour, sugar, granules, or regrind. They are commonly used in the plastics industry (protection of injection molding machines and extruders). They protect machines from failure and ensure high quality of the final product.
Induction of around 6000 Gs is an economical choice for catching distinct contaminants. If you need to remove microscopic filings, iron oxides, or stainless steel after mechanical processing, choose High Power. 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. Metal holds strongly, so packing tape can be helpful, which we stick to the roller and tear off together with the filings. We recommend frequent checks of the filter's contamination status, e.g., once per work shift.
Yes, we are a manufacturer and make grates to any size and shape. We deliver complete filtration solutions, ready to be plugged into the installation. 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 as well as weaknesses of neodymium magnets.

Pros

Besides their remarkable strength, neodymium magnets offer the following advantages:
  • They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
  • They maintain their magnetic properties even under close interference source,
  • Thanks to the smooth finish, the layer of nickel, gold, or silver gives an clean appearance,
  • They show high magnetic induction at the operating surface, which improves attraction properties,
  • 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...
  • Possibility of custom forming and modifying to complex applications,
  • Significant place in modern technologies – they are utilized in computer drives, drive modules, advanced medical instruments, also industrial machines.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
  • Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these devices can complicate diagnosis medical after entering the body.
  • Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Maximum holding power of the magnet – what affects it?

Magnet power is the result of a measurement for ideal contact conditions, including:
  • on a plate made of mild steel, perfectly concentrating the magnetic flux
  • with a cross-section no less than 10 mm
  • with an ideally smooth contact surface
  • under conditions of no distance (surface-to-surface)
  • during pulling in a direction perpendicular to the mounting surface
  • at ambient temperature approx. 20 degrees Celsius

Key elements affecting lifting force

It is worth knowing that the application force may be lower subject to elements below, in order of importance:
  • Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
  • Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets
Skin irritation risks

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.

Machining danger

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Crushing risk

Watch your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!

ICD Warning

Patients with a heart stimulator should maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.

Electronic hazard

Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Caution required

Use magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and respect their power.

Material brittleness

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Danger to the youngest

Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Keep away from children and animals.

Maximum temperature

Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.

GPS Danger

Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
