Abstract
A device for removing impurities from shredded plastic includes at least one first cleaning body having a sectionally tapered and/or cylindrical outer surface forming a first cleaning surface, and at least one second cleaning body having a sectionally tapered and/or cylindrical inner surface forming a second cleaning surface. The second cleaning body accommodates the first cleaning body such that the cleaning surfaces oppose each other and delimit a cleaning gap between each other. A drive apparatus can rotate at least one of the cleaning bodies about its longitudinal axis, and a feed apparatus feeds the shredded plastic into the cleaning gap. The cleaning surfaces each have cleaning ribs, wherein at least one flank of the cleaning ribs is inclined or curved. Cleaning bars running transversally to the direction of extension of the cleaning ribs are arranged between at least some neighboring cleaning ribs.
