It is a device used to catch unwanted metals from bulk raw materials transported on a belt. It is usually mounted above the conveyor belt (so-called overbelt) or in chutes. Ensures high quality of the final product in plastic recycling, wood, and the food industry.

Ferrite magnets work effectively at a greater distance (high suspension), but with less surface force. 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 decision should be made based on the type of separated material and cleanliness requirements.

The separator housing is high-quality stainless steel, welded by TIG method. This guarantees hygiene and ease of cleaning, which is crucial in the food industry. It can be safely used in contact with loose food (flour, sugar, grain).

It is a device operated manually by an operator. Just drop attracted elements (screws, wires) outside the conveyor belt area. Cleaning frequency depends on the amount of contaminants in the product - the more metal, the more often you need to clean.

Yes, we are a manufacturer and make plate separators to any size. We adjust length, width, and mounting hole arrangement (eyes, threads). Contact us to receive a free quote and technical drawing.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose strength, even over around ten years – the reduction in power is only ~1% (according to tests),
Magnets very well protect themselves against loss of magnetization caused by ambient magnetic noise,
In other words, due to the glossy finish of nickel, the element becomes visually attractive,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of exact forming and modifying to complex requirements,
Wide application in future technologies – they find application in magnetic memories, drive modules, diagnostic systems, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in miniature devices

Disadvantages

What to avoid - cons of neodymium magnets and proposals for their use:

At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic holder.
Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
Due to complex production process, their price is higher than average,

Holding force characteristics

Maximum magnetic pulling force – what it depends on?

Information about lifting capacity is the result of a measurement for ideal contact conditions, including:

with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
with a cross-section minimum 10 mm
with a surface cleaned and smooth
with direct contact (without impurities)
for force applied at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

Effective lifting capacity is affected by working environment parameters, mainly (from priority):

Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Base massiveness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted to the other side.
Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safe handling of neodymium magnets

Power loss in heat

Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Shattering risk

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Adults only

Always keep magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are life-threatening.

Caution required

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Physical harm

Big blocks can smash fingers in a fraction of a second. Do not put your hand between two attracting surfaces.

Impact on smartphones

GPS units and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Allergy Warning

A percentage of the population experience a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Extended handling can result in skin redness. We strongly advise wear protective gloves.

Health Danger

Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Cards and drives

Device Safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Fire risk

Powder created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
