IFE launches new generation of eddy current separators

IFE presents its latest development at this year's IFAT with LIVE DEMONSTRATION: the eddy current separator "ENOS"

The dominant opinion prevailing in the eddy current separator industry, namely that a higher poling frequency equates to a higher sorting quality, is causing some to look at the developments of the products available on the market with skepticism. More and more, the manufacturers of eddy current separators are steadily increasing the number of poles of their rotors and also their operating speed, presumably in order to serve the need for sortability of grain sizes under 1mm.

For over 70 years, the IFE Aufbereitungstechnik GmbH, has stood for values such as robustness, longevity and process reliability. The company is deliberately counteracting this trend and taking a different approach by fundamentally researching eddy current sorting technologies.

Essentially, the variety of shapes, groupings and structures in the secondary residue fraction does not allow a purely theoretical exploration and treatment of physical laws. The strong variance of the particle shapes results in a strong variability in the trajectory of the particles. For this reason and in addition to the extensive hypothetical analysis, IFE also invested a significant amount of resources in field research and decided to implement a trajectory evaluation based on high-speed camera technology. Using this tool, flight paths of particles can be captured with a high-speed camera and then recorded as trajectories. Thus, the most varied particle shapes and materials are able to be parameterized and analyzed by software according to relationships and cross-relationships.

This trajectory evaluation made it possible to determine those parameters and influencing variables that allow an actual influencing of the radial and tangential repulsive force, as well as the resulting moment to be possible. These findings enabled IFE to carry out the technical implementation, which specifically controls a reduction in scattering or an influence on the resulting force vector, for example. This laid the foundation for the development of the new eddy current separator generation.

In the course of the research, the previous top product, the IFE STRATOS, was optimized and further developed into a universally applicable eddy current separator (e.g. non-ferrous removal from scrap, biomass and waste wood).

New in the product portfolio is an eddy current separator named IFE VIOS. This separator utilizes an absolutely new geometry of pole changing which causes a previously unprecedented repulsive force in the non-ferrous parts to be separated. This technology exceeds the sorting result of conventional eddy current Separators. Targeted parameterization allows this rotor to also able to concentrate different non-ferrous metals from each other or even PCBs from non-ferrous metals.

Last but not least the IFE ENOS, which will also be on display live at this year's IFAT, complements the broad product range. This eddy current separator is based on a completely different parameterization to all conventional products. It features extremely high throughput rates and outstanding sorting quality, as well as simultaneous separation of stainless steels in one pass.

This product family broadly positions the IFE Aufbereitungstechnik in the field of eddy current sorting and allows it to cover a wide range of non-ferrous sorting applications. A flexible machine concept developed according to the latest findings is now available for a wide range of requirements. In the future, IFE's focus will be on optimizing the application of the Portfolio.
