13 Nov Goodbye magnesium – How to process aluminium scrap even more efficiently
Shared by Luigino Menegatti
Sorting technology specialist Steinert has managed to reduce the fractions of magnesium in the aluminium scrap flow by 92%. This is thanks to a technical upgrade of its x-ray transmission sorting system Steinert XSS T.
The magnesium (die-cast components) can now either be extracted separately as a concentrate or can be sorted, for example into the cast aluminium fraction. This application can now be integrated into aluminium scrap sorting systems treating end-of-life vehicles and mixed scrap, etc.
The innovative sorter operates at throughputs of 3 to 8 t/h per metre – just like the original Steinert XSS T model. It therefore ensures much more efficient sorting without any loss of processing capacity. Steinert adds that this new sorting task can be performed in the grain sizes of 10 – 30 mm, 30 – 70 mm and 70 – 130 mm; where the main share of magnesium is found.
Also, Steinert says it is able to retrofit sorting equipment produced from 2016 onwards at recycling sites.
