Permanent overband magnetic plates DND-AC
Conveyor magnetic separator with automatic cleaning is designed to handle product stream with a high content of ferromagnetic particles (exceeding the limitation of standard suspended plate magnets).
It is designed to capture in a quick and easy way valuable ferromagnetic particles from a product stream and at the same time the overband magnetic plate with automatic cleaning protects your machinery (shredders, mills, grinders, screw conveyors etc.) that subsequently treat the material. The tramp ferrous metal extracted from the conveyor is removed by a heavy duty rubber belt into a skip or a collection bin at the side of the conveyor.

Recommendation: Connection of a magnetic plate and magnetic roll
In order to achieve the highest possible degree of separation, it is recommended that – especially in case of a higher layer of material on the conveyor belt – the overband magnet DND is combined with the magnetic pulley MV (that is able to attract ferromagnetic particles from lower material layers).
Installation of magnetic plate
Most commonly the overband magnetic separator DND-AC is suspended above and across the belt, however it is also possible to place it at the head of the conveyor (parallel to the belt). The kind of applied magnets depends on the position of the separator: if the magnetic separator is parallel to the conveyor belt.
It is possible to use weaker magnets (as at the end of the conveyor belt the material is quite loose). On the contrary, if the magnetic separator is suspended across the belt, we recommend that stronger magnets are applied (as the material layer on the belt might be higher and compacter)
The standard version of the overband magnetic separator DND-AC M is fitted with strong permanent ferrite magnets. However, if you need stronger magnetic force (e. g. for mobile lines, grinders, mills), we recommend that the overband magnetic separator is equipped with extremely powerful neodymium NdFeB magnets from rare earth ores. A careful interference shielding ensures that the magnetic field is concentrated only on the material on the conveyor belt.
In total there are eight types of DND-AC self-cleaning overband magnets (five ferrite and three neodymium ones, see below), so that even standard products can satisfy the needs and requirements of the broadest possible spectrum of clients. At the same time, our customers can be sure that the parameters of the product are in accordance with their needs and that they will not pay extra money for an above standard equipment that would be unnecessary for their specific application.
Ferrite ovebands
The main benefits of ferrite overband magnets include the following: high temperature resistence, long-term magnetic stability, affordable price, deep and very strong magnetic field (in case of stronger models).
DND-AC M F - PANTHER
Combines a standard performance with an interesting price. These separators are intended for medium-duty applications with the maximum installation height of 200 mm, and they are capable of trapping larger ferromagnetic particles (above 1 mm). A very good rate of return (price/performance ratio) is a significant benefit of this kind of plate.

DND-AC Mx F - BEAST
Is the strongest of all SOLLAU magnetic overband separators. Magnetic induction of these devices is at the limit of the capabilities of the strongest permanent magnets and can only be surpassed by electromagnetic separators. This series is intended for the most challenging separation from extreme depths and high and heavy material layers. The maximum suspension height of these devices is 450 mm (an interesting fact: the strongest ferrite DND-AC Mx F series is approximately five times heavier than the lightest DND-AC M F series!).

DND-AC EKO
Overband magnetic separator DND-AC EKO is a low-cost variant of an overband magnet. From the magnetic point of view there is no difference between the standard version DND-AC and the economic version DND-AC EKO.
Both generate the same magnetic induction (what is quite exceptional, as the economic models of our competitors are generally magnetically weaker in comparison with their standard models). On the other hand, the clients acquiring our DND-AC EKO version have to accept the fact that this model is equipped with the engine CANTONI and with the gearbox VARVEL, there are unprotected bearings and only the bottom part of the separator is protected by metal sheets.
DND-AC EKO is designed to handle product stream with a high content of ferromagnetic particles (exceeding the capacities of the manually cleaned magnetic plates). This separator can capture in a quick and easy way valuable ferromagnetic particles from a product stream and at the same time the overband magnetic plate with automatic cleaning protects your machinery (shredders, mills, grinders, screw conveyors etc.) that subsequently treat the material. The tramp ferrous metal extracted from the conveyor is removed by a heavy duty rubber belt into a skip or a collection bin at the side of the conveyor.

Neodymium overbands
An extremely strong (but relatively short) magnetic field and a low weight are the most significant benefits of neodymium overband separators. That is why the application of the neodymium separators is preferred at the places where it would not be possible to use heavy ferrite magnets or where a very high separation efficiency at shallower depths is required (e. g., in cases of mobile crushing and recycling lines).
DND-AC N JACKAL
Is the lightest series intended for the maximum suspension height of 200 mm. This separator is even able to trap Fe particles smaller than 1 mm (at shallower depths).
