For recyclers who sort metals and alloys, in applications where precise understanding of content and composition is paramount, X-ray fluorescence (XRF) based handheld analyzers have been the main tool employed for over a decade. In recent years, however, laser-induced breakdown spectroscopy (LIBS) technology has been used increasingly in metal recycling applications, especially with aluminum and other nonferrous metals, and for light elements. XRF is still considered by most to be the best option for applications in stainless steel and heavy metals, or for recyclers focused on plastics and e-waste sorting.
The latest generation DELTA Alloy Analyzer has an ergonomically advanced design incorporating the latest in electronics, components and software technology. These units also feature better sensitivity and precision, in faster time for more materials, than previous models.
Sorting equipment provider Steinert recently announced the successful installation of their first XSS-F, an in-line system designed to extract copper (so-called ‘meatballs’) from shredded ferrous scrap. Installed in-line at a German recycling yard, this new technology is capable of processing high volumes of steel scrap directly out of the shredder.
