This type of magnetic separator is intended for trapping metallic magnetic particles in a stream of mainly liquid substances. It is fitted with very strong permanent magnets in order to prevent in carrying magnetic particles away by a stream of liquid. These are rare-earth magnets NdFeB that have several times higher magnetic induction (magnetic force) when compared with standard ferritic magnets which would not be able to hold metallic particles from liquid.
As a standard, we produce separators with input and output diameters of 50, 100, 150 and 250 mm. Magnetic separators can also be delivered in a two-shell design for internal shell heating (separation e.g. from chocolate).
Separator automatic cleaning
After start of automatic cleaning process, the magnetic cores are shifted out from the stainless steel tubes in the upper portion of the magnetic separator. Washing out water will remove the trapped metallic particles completely and these particles can be discharged from the separator through the valve in the bottom part. Before starting the cleaning process, it is possible to utilize another valve through which you can discharge residual material which remains in the body of the magnetic separator before its cleaning.
The magnetic separator is controlled by means of FESTO pneumatic elements and the cleaning process is controlled via SIEMENS electronic system.

Course of the separation in the separation vessel
Magnetic separator with the automatic cleaning is capable of catching of metal impurities from liquids. During the automatic cleaning cycle, impurities are rinsed by water or any suitable medium. This rinsing liquid, together with the caught metals, is released to the separation tank (see the red supply line in the picture).
Magnetic drum is situated in the upper part of the separation vessel (in red). Through this magnetic drum, rinsing liquid is flowing to the lower part of the vessel (in green). Magnetic drum catches the metal particles and pushing cylinder pushes remaining liquid from them. Due to that, assorted metals are almost dry and they accumulate in the attached vessel (the grey one).
Great benefit of this technical solution consists in the fact that the rinsing liquid located in the lower vessel part is then used again for the separator cleaning. It is, therefore, a closed circuit with minimum losses of the rinsing liquid. Liquid adding or complete replacement can take place just from time to time that means cutting of the costs and no needs for a further operation.
Where the separation vessel should be used?
In any situation when the rinsing liquid, contaminated with caught metal impurities, cannot be discharged to the sewage system.
