Sesotec metal separators and magnet systems protect extruders from damage that can be caused by metal particles in the plastic granulate, even when enclosed in the product. Equipment stoppages and production downtime caused by plugging of melt filters and nozzles are reduced.



A magnetic separator for high material throughputs, and larger column diameters (40 - 120 mm) and particle sizes (8 - 10 mm), the EXTRACTOR-SE is installed at the feedstock intake of the extruder and is used to remove ferrous materials prior to processing.

GF
These metal separators are designed to be installed in horizontal, vertical or inclined vacuum and pressure pipes. Detection and removal of contaminants is effective even at high speeds and rejected material is removed into a container with no interruption to material flow.

GMT
An economical permanent magnet system installed at the feedstock intake of the extruder, the GMT eliminates larger particles of ferrous metals to produce a higher quality product and reduce expensive repairs.

MAGBOX inline magnets are mainly installed in existing pipeline systems to remove fine and very fine ferrous metal contaminants from bulk materials.

RAPID COMPACT metal separation systems remove magnetic and non-magnetic metal particles (steel, stainless steel, aluminium etc) from free-falling bulk materials. Metal contaminants (even those contained in granulate) are removed by means of a reject flap (‘Quick Flap System’) without any interruption to the material flow. The RAPID COMPACT range is mainly used in industries where hygiene standards are less important. They are used to inspect dry bulk materials with little or no product effect.

The RAPID PRO-SENSE metal separator primarily is used for quality inspection (product purity) in the production and compounding of plastic granulate, where it typically is installed directly before the material is filled in bigbags, octabins, or silos. The metal separator also is used for quality inspection in the incoming goods department of plastic-processing plants (product purity, machine protection).

A metal separator with product effect compensation, the RAPID VARIO-FS is installed at the feedstock intake of the extruder. Because the detection and separation units are separate, the system can be adapted to many different configurations and conditions.

The SAFEMAG inline magnet was developed specifically for applications in the plastics industry. It is designed for inspecting different granulates up to a grain size of 6-8 mm at a temperature of up to 100°C in standing or slow-moving material columns.
