A low-intensity Drum Magnet and high-intensity Rare Earth Roll Magnetic Separator separating strong (including mild steel) and weakly magnetic metals (such as fragmented stainless-steel) from a fines fraction extracted as waste after shredding. The non-magnetic metals are further processed on an ElectroStatic Separator.
