Sensor-based sorting solutions protect customers from losing sales on volatile export markets. And not just in times of crisis because purity and product quality ensure the commercialisation of secondary scrap. The new e-book from the sorting specialist Steinert explains how to separate non-ferrous metals and heavy metals to the maximum.
“Customers that commit to maximum quality when sorting secondary scrap can get a real head start in commercialising their products,” predicts Karl Hoffmann, Sales Director for Metal Recycling at Steinert. X-ray transmission and X-ray fluorescence are the two technologies used to produce pure fractions from aluminium, copper, zinc and brass.
For example, advanced X-ray transmission sorting can be used to remove free magnesium from aluminium scrap, thereby producing high-purity qualities ready for the furnace. The application has been up and running in customer plants for a year now and is producing a verifiable magnesium enrichment rate of up to 94 %. This is an effective and flexible alternative to sorting by density in a sink/float procedure.
The technical application can be retrofitted on most STEINERT XSS-T X-ray transmission sorting systems built from 2016 and later and is already being used by many customers.
