The magnetic separator with automatic cleaning is designed to capture magnetic metal contaminants, particularly in streams of liquid substances. It is equipped with very strong permanent magnets to prevent the liquid flow from dislodging the captured magnetic contaminants.
These are neodymium NdFeB magnets, which provide several times higher magnetic flux density than conventional ferrite magnets, which would be unable to retain metal contaminants in the liquid.
We usually manufacture units with inlet and outlet diameters of 50, 100, 150 and 250 mm. The magnetic separator can also be supplied in a double-jacketed design for heating the inner jacket (e.g. for separation from chocolate).
The magnetic separator is operated by FESTO pneumatic components, and the cleaning process is controlled by a SIEMENS programmable logic controller (PLC).
When the automatic cleaning process is started, the magnetic cores are withdrawn from the stainless-steel tubes into the upper section of the magnetic separator. Rinsing water thoroughly removes the captured metal contaminants, which are then discharged from the separator through a valve in the lower section.
Before starting the cleaning process, another valve can be used to drain any residual material remaining in the magnetic separator body.

Secondary separation of metal contaminants captured by a flow-through separator with automatic cleaning.
Magnetic separator with automatic cleaning captures metal contaminants from the liquid. During the automatic cleaning cycle, these contaminants are rinsed off with water or any other medium. This rinsing liquid, together with the captured metals, is discharged into the separation vessel.
A magnetic drum is located in the upper section of the separation vessel. The rinsing liquid flows over this magnetic drum into the lower section of the vessel. The magnetic drum captures the metals, and a pressure roller squeezes out the remaining liquid. As a result, the separated metals are almost dry and are collected in the supplied container.
A major advantage of this technical solution is that the rinsing liquid from the lower section of the vessel is reused to rinse the separator. This creates a closed circuit with minimal rinsing-liquid losses.
It is suitable wherever rinsing liquid contaminated with captured metal contaminants cannot be discharged into the sewer system.
The magnetic drum captures the metals, and the pressure roller squeezes out the remaining liquid.
The separator is suitable for capturing magnetic metal contaminants from liquid substances where the contaminants must not be dislodged by the liquid flow. It is also suitable for applications requiring automatic cleaning without manual operation.
When choosing a separator, it is important to consider the type of liquid, flow rate, inlet and outlet diameter, automatic-cleaning requirements, the need for a heated double-jacketed design and the option of using a separation vessel.
We will design a suitable solution including automatic cleaning, a bypass, a double-jacketed design for heating and a closed-loop system with a separation vessel.
