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 magnets work effectively at a greater distance (high suspension), but with less surface force. They work well in initial separation in recycling and mining. 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 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. The product meets standards for the food industry (HACCP/IFS/BRC).
Removing contaminants is simple but requires periodic stopping of the process or access to the magnet. Scrap is removed by mechanically moving it to the edge, where the magnetic field is weaker. To facilitate, a cleaning overlay (dump drawer) can be used, which we offer as an option.
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.

Pros as well as cons of neodymium magnets.

Benefits

Apart from their strong power, neodymium magnets have these key benefits:
  • They retain magnetic properties for nearly ten years – the loss is just ~1% (based on simulations),
  • They are extremely resistant to demagnetization induced by external magnetic fields,
  • By applying a shiny coating of gold, the element has an aesthetic look,
  • Magnetic induction on the working part of the magnet turns out to be maximum,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Due to the possibility of precise shaping and customization to individualized solutions, neodymium magnets can be created in a wide range of shapes and sizes, which makes them more universal,
  • Wide application in electronics industry – they find application in mass storage devices, motor assemblies, precision medical tools, and industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:
  • At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • We recommend cover - magnetic mount, due to difficulties in creating threads inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products can complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Best holding force of the magnet in ideal parameters – what affects it?

The load parameter shown represents the peak performance, recorded under optimal environment, meaning:
  • on a base made of mild steel, perfectly concentrating the magnetic field
  • with a thickness minimum 10 mm
  • characterized by lack of roughness
  • with total lack of distance (without impurities)
  • during pulling in a direction perpendicular to the plane
  • in stable room temperature

Lifting capacity in real conditions – factors

Real force is influenced by specific conditions, such as (from most important):
  • Gap (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
  • Direction of force – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
  • Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
  • Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.

Warnings
Power loss in heat

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Do not drill into magnets

Machining of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Powerful field

Be careful. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can react.

Phone sensors

GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.

Pinching danger

Big blocks can crush fingers instantly. Never put your hand between two attracting surfaces.

Avoid contact if allergic

A percentage of the population experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Extended handling can result in skin redness. It is best to wear protective gloves.

Swallowing risk

Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them breaking into shards.

Magnetic media

Do not bring magnets near a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.

Pacemakers

Individuals with a pacemaker have to keep an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
