TOMRA launches new X-TRACT X6 FINES machine, capable of sorting metal fractions of unprecedented smallness

TOMRA Sorting Recycling has launched a new machine, the X-TRACT X6 FINES, for the high-purity sorting of mixed non-ferrous metal fractions at Aluminum USA, the biannual industry event staged at the Music City Center convention center in Nashville, Tennessee.

The X-TRACT X6 FINES can detect and sort grains of metal of almost half the size of what was previously sortable. This unprecedented capability has been achieved by developing TOMRA’s exclusive and field-proven high-speed X-ray transmission (XRT) technology, which sorts materials according to differences in their density. Broad-band radiation penetrates the materials in the sorting line to obtain spectral absorption information, which is measured by an X-ray camera. Within this process, the atomic density of the materials is identified regardless of their thickness.

Increasing the sensitivity of the high-resolution X-ray camera has made it possible to detect and sort grain sizes as small as 5 – 40 mm, thus measurably reducing product losses. Extensive validation runs of the X-TRACT X6 FINES in high-throughput applications demonstrated the machine’s ability to consistently attain unrivalled purity levels of 98 – 99 %.

Like X-TRACT, X-TRACT X6 FINES is equipped with TOMRA’s Duoline® Dual ENERGY Techno-logy. This employs two independent devices with different spectral sensitivities, so that materials are sorted regardless of the material’s thickness. By detecting and prioritizing between single object processing and area processing, Duoline® recognizes differences in objects overlapping on the sorting line, a significant advantage when lines are running higher throughputs.

Another useful advantage is the provision of multi-density channels. Whereas previous X-TRACT models sorted materials according to two classes, separating it into high-density and low-density fractions, the new X-TRACT X6 FINES features multiple density channels. This allows a greater number of classes for separating materials according to density, achieving greater sorting precision even with mixed metals and small grain sizes.

Valerio Sama, Vice President and Head of Product Management Recycling at TOMRA, commented: “The smallness of the metal grains that can now be detected and sorted by TOMRA’s X-TRACT technology is unrivalled. This will enable sorting operations to unlock even more value from secondary materials. But while our X-ray sorting technology reaches new levels of sophistication, the new X-TRACT X6 FINES retains the familiar controls of the standard X-TRACT and brings the peace of mind that comes with an industry-proven technology.”
