Permanent overband magnets for mobile crushers and screeners
We have long experience with the production of overband magnets for mobile crushers and screeners.
We have supplied hundreds of magnetic separators to the largest recycling companies worldwide. We are proud to be a supplier of magnetic technologies for leading manufacturers of mobile crushers and screeners.
And that is why we know well what the customers expect from our overband magnets:
- 1Low weight – compact devices from 480 kg
- 2High performance and efficiency – magnetic induction up to 910 Gs (at a distance of 200 mm from the magnet)
- 3Small compact dimensions – easy installation in the production line
- 4Possibility to choose the magnetic core – the overband magnet can be fitted with extremely strong neodymium magnets (low weight, high performance, small dimensions) or with standard ferrite magnets (economical alternative; excellent price/performance ratio)
- 5Low price – we believe that our prices will be interesting for you
- 6Short delivery times – we have large production capacities
- 7Quality – we provide a 10-year warranty on the magnetic cores of our separatorss
- 8Possible customized production in your design (private label) – the colour, logo, marking, design, motor type, suspension mode – all is up to your choice
- 9Optional equipment – a wide range of additional accessories according to your requirements
We have our own development department so we are able to design a separator precisely for you. We take pride in meeting specific customer requirements so that the separator is fully compatible with your mobile line.
Benefits of using the overband magnets
- Material without iron contamination
- Permanent protection of production equipment (e. g. crushers)
- Continuous production operation
- Automatic cleaning without the interruption of the material flow
- Elimination of operator errors

We fit our separators either with ferrite or very strong neodymium magnets. We always care about the customer's needs.
Separators with ferrite magnets an economical variant of the product and are characterized by an excellent price/performance ratio. They are strong and reliable.
We often fit these separators with strong neodymium magnets. That is why these separators are characterized by low weight, small dimensions and extreme magnetic induction = high separation efficiency (and all these properties are appreciated by the manufacturers of mobile recycling systems).
The weight of our smallest overband is only 480 kg while maintaining a high separation efficiency. We most often produce overband magnets for belt conveyors of 1,000, 1,200 and 1,400 mm, but we are not afraid of challenges and are ready to design a tailor-made separator exactly for your technology.
The waterproof magnetic cores guarantee long service life of our appliances. The compact separator design with a minimum of cavities (where the material could accumulate) ensures its trouble-free operation.
Motor types (the devices can be supplied with various types of motors):
- electric motor with a gearbox
- hydraulic motor
- electric cylinder
Options (basic overview):
- Central lubrication
- Discharge pole (only at neodymium versions) for lower belt wear and reliable removal of the captured metals
- All-stainless steel design
- Belt alignment control
- Belt break control
We manufacture the overbands magnetic separators according to the requirements of our customers, so the list of optional variants is much more extensive.
We are aware of the fact that it is essential for our customers to know the magnet performance at different distances from the magnetic separator. Therefore, we state magnetic induction values not only at the magnetic core, but at a distance of 0 to 500 mm from the magnet (measured in 50 mm increments). Our strongest overband magnet is characterized by the magnetic induction of 910 G at a distance of 200 mm from the magnetic core.
We also test and measure the ability of overband magnets to attract diverse types of ferromagnetic objects from various distances.
SOLLAU – our products are welded by real professionals!
SOLLAU certifications:
Authorization to perform welding on pressure equipment according to PED 2014 / 68 / EU
Pressure welder certificate according to EN-ISO 3834 - 2, EN 1090 - 2, EN 13480 - 1 to 5, EN 13445 - 1 to 5
The standard magnetic plate DND-AC is designed for stationary belt conveyors. The self-cleaning overband magnet for mobile crushers and screeners is engineered for the demands of mobile operation — compact design with minimal cavities, a waterproof magnetic core, low weight from 480 kg and the option of hydraulic drive ensure trouble-free operation even in field conditions. We manufacture the separator precisely to fit the specific mobile machine so that it is fully compatible with your line.
We install the magnet at a height of up to 450 mm above the conveyor belt. At an installation height of 200 mm, the magnetic flux density reaches 910 G, capturing ferromagnetic particles from 0.5 mm. Measured flux density values at distances of 0–500 mm from the core (in 50 mm steps) are supplied with every separator as part of the test report.
The ferrite version offers an excellent price-to-performance ratio and is suitable where minimising weight or dimensions is not critical. The neodymium version achieves significantly lower weight and smaller dimensions with extreme magnetic performance — which is why it is preferred by manufacturers of mobile equipment where every kilogram matters. We always tailor our recommendation to the specific application and customer requirements.
We supply the separator with an electric motor with gearbox, hydraulic motor or electric cylinder. The choice of drive depends on the hydraulic or electrical infrastructure of your mobile line. We design the drive as part of an individual solution so that the separator is fully compatible with your machine.
Yes, we can adapt the colour, logo, labelling, design, drive type and magnet suspension to your requirements. We are a supplier of magnetic technology to leading global manufacturers of mobile crushers and screeners and have many years of experience producing separators in customer designs. Simply contact us and we will prepare an individual quotation.
The waterproof magnetic core guarantees a long service life of the equipment even in dusty and humid environments. The compact design with minimal cavities prevents material from getting trapped in the structure. Optionally, we supply central lubrication, a discharge pole to reduce belt wear, belt tracking and breakage monitoring, or a full stainless-steel version.
We provide a 10-year warranty on the magnetic core. Before delivery, every separator is thoroughly tested and the magnetic flux density is measured at distances of 0–500 mm from the magnet — not only at the core but at real working distances. A test report with the measured values is supplied with the separator.
The separator is used in recycling and waste processing, the mining industry and quarries, the wood processing industry and concrete crushing (capturing steel rebar). It protects crushers and downstream processing equipment from damage by metal objects and ensures the end product is free of ferromagnetic contaminants.
