Mechanical processing of aluminum scrap (1) comprises: (i) grinding of the aluminum scrap, (ii) supplying the shredded aluminum scrap to a screening system and dividing into a fraction of undersized materials and a fraction of oversized materials, (iii) homogenizing the fraction of oversized materials; (iv) subjecting the homogenized fraction of oversized materials to a density determination by X-ray transmission; (v) pneumatically sorting out the material to be sorted with a temperature above a predetermined threshold density; and (vi) separating non-ferrous separator residues. Mechanical processing of aluminum scrap (1) comprises: (i) grinding of the aluminum scrap, (ii) supplying the shredded aluminum scrap to a screening system and dividing into a fraction of undersized materials and a fraction of oversized materials, (iii) homogenizing the fraction of oversized materials; (iv) subjecting the homogenized fraction of oversized materials as a material to be sorted in X-ray device to a density determination by X-ray transmission; (v) pneumatically sorting out the material to be sorted with a temperature above a predetermined threshold density; and (vi) separating non-ferrous separator residues from the remaining residual fraction. An independent claim is also included for a device for the mechanical processing of aluminum scrap, comprising a crushing device (2) for crushing the aluminum scrap, a screening plant downstream of the crushing device, X-ray device and a separator equipped with a pneumatic nozzle device, where the nozzle device is controllable depending on difference of the radiation intensity determined by the X-ray device using the X-ray transmission. |
