Suspended magnets DND-MC
Suspended permanent magnet with manual cleaning is the simplest and cheapest equipment for the separation of ferromagnetic particles from materials transported on a belt conveyor. This permanent magnetic separator is suitable for materials with lower content of magnetic metal particles (if the cleaning is not required more often than once a work shift).
How is the suspension magnet cleaned?
The magnetic plate is suspended above the belt conveyor and the magnetic impurities are captured at the bottom of the magnetic plate (usually fitted with strong permanent ferrite magnets, however on client's requirement is is possible to use extremely strong neodymium NdFeB magnets). The ferrous particles accumulated on the surface of the magnetic plate are removed manually. If the material contains too many ferromagnetic particles, the magnetic plate is swiftly clogged with ferrous particles. In this case we recommend that the clients opt for our overband magnetic separator DND-AC with automatic cleaning.
Easy cleaning suspended magnet DND-MC
DND-MC magnetic plate can be equipped (at extra charge) with a cleaning stripper tray for simple removal of the trapped magnetic particles. On the bottom of the cleaning stripper tray (that protects the magnetic core steel plate) there are longitudinal steel slats that prevent the captured ferromagnetic particles from jumping onto the magnetic core steel plate during the cleaning (when the cleaning stripper tray is being drawn out) and also ensure uniform distribution of the trapped ferrous material on the stripper tray surface.
Dimensions of the permanent suspension magnet
The magnetic plate with manual cleaning can be made in any size according to customer's needs.
Suspended magnet on a rail construction
Manual cleaning permanent magnetic separator on a special rail construction is a sophisticated version of the suspended magnet. Thanks to the rail construction it is possible to move the magnetic plate aside and carry out the cleaning or maintenance in a very easy and safe way even without stoppage of the conveyor belt.
Combination of a suspension magnet with a magnetic pulley
In order to achieve the most efficient iron tramp separation in case of a high layer of the transported material, we recommend to combine the use of the magnetic plate with our magnetic pulley MV that can separate the ferromagnetic particles also from lower layers of the transported material.

Ferrite suspension magnets
The main benefits of ferrite magnetic plates include the following: high temperature resistance, long-term magnetic stability, affordable price, deep and very strong magnetic field (in case of stronger models).
DND-MC M F
- Installation height up to 200 mm
- Lower weight
- Capturing ferromagnetic particles bigger than 1 mm
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.

Neodymium suspension magnets
An extremely strong (but relatively short) magnetic field and a low weight are the most significant benefits of neodymium suspension magnets. That is why the application of the neodymium plates is preferred at the places where it would not be possible to use heavy ferrite plates or where a very high separation efficiency at shallower depths is required (e. g., in cases of mobile crushing and recycling lines).
DND-MC N
- Installation height up to 200 mm
- Capturing ferromagnetic particles bigger than 0.5 mm
Is the lightest series intended for the maximum suspension height of 200 mm. This plate is even able to trap Fe particles smaller than 1 mm (at shallower depths).

The DND-MC is the right choice when ferromagnetic contaminants do not require cleaning more than once per work shift. For higher volumes of metal impurities or continuous operation where the conveyor cannot be stopped, the self-cleaning suspended magnet DND-AC is the correct solution.
Ferrite magnets (series M F to Mx F) are suitable for installation heights of 200–450 mm and capture contaminants larger than 1 mm. Neodymium magnets (series N, Ns, Nm) are lighter and generate a stronger field at short distances – they are installed up to 250 mm and capture contaminants from 0.5 mm. We recommend neodymium variants where the weight of the ferrite magnet exceeds the load capacity of the structure.
The suspended magnet DND-MC captures ferromagnetic contaminants from 0.5 mm (neodymium series) up to a distance of 300 mm; the exact capture range depends on the selected model series and installation height. The maximum recommended conveyor belt speed is 3 m/s.
Captured contaminants are removed manually – the frequency depends on the volume of metal impurities, typically once per shift or less. As an option, the magnet can be equipped with a sliding cleaning plate for faster cleaning, or mounted on a rail structure and pulled aside without stopping the conveyor.
We offer DND-MC magnets for belt conveyor widths from 500 mm to 2,000 mm; they can be installed transversely or longitudinally above the belt. Selected models are kept in stock permanently, and we also manufacture them in custom dimensions.
When the material layer on the belt is thick, the magnet preferentially captures contaminants from the upper layers. To capture metals from the lower layers, we recommend adding a magnetic separation drum at the end of the conveyor alongside the DND-MC.
We provide a 10-year warranty on suspended magnets DND-MC. Delivery includes comprehensive care from custom design and manufacturing through installation and training to authorised service; we test your material on the separator free of charge with results delivered within three days.
Which industrial branches can the suspended magnets be used in?
This manual cleaning permanent magnetic separator finds use in recycling, mining, plastic, glass and wood industries.
