1. A device for removing impurities from shredded plastic (56) comprising a first cleaning disk (10) with a first cleaning surface (12), and a second cleaning disk (40) with a second cleaning surface (42), wherein the cleaning surfaces (12, 42) are opposite each other and delimit a cleaning gap (44) between each other, furthermore comprising a drive device by means of which at least one of the cleaning disks (12, 42) is rotatable about its rotational axis (22), and a feed device by means of which the shredded plastic (56) can be fed between the cleaning disks (10, 40), wherein:
the cleaning surfaces (12, 42) of the cleaning disks (10, 40) each have a plurality of cleaning ribs (18, 46) extending between an inner and outer edge (14, 16) of the cleaning surfaces (12, 42), wherein at least one flank (24, 28) of the cleaning ribs (18, 46) is angled or curved relative to the axial direction of the respective cleaning disk (10, 40), and a plurality of cleaning bars (20, 48) running transversally to the direction of extension of the cleaning ribs (18, 46) are arranged between at least some cleaning ribs (18, 46) neighboring each other. |
