Title: DEVICE AND METHOD FOR SORTING
Abstract:
The invention relates to a device (1) and a method for sorting, in particular crushed, aluminium scrap (2) according to alloy groups (6.1, 6.2, 6.3), in which method the aluminium scrap (2) is divided into fractions (4), the fractions (4) of aluminium scrap (2) are irradiated by at least one neutron source (9), the gamma radiation (10) emitted from the individual fractions (4) via this neutron irradiation is received by a respective at least one detector (11), and an energy spectrum associated with each fraction (4) is formed from this, on the basis of which energy spectrum a relative ratio of the weight proportions of at least two alloy elements of this fraction (4) is determined, and this fraction (4) is assigned to the corresponding alloy group (6.1, 6.2, 6.3) based on this relative ratio, and the fractions (4) are then sorted according to the alloy groups (6.1, 6.2, 6.3) assigned to them.
