<p>The method involves arranging an individual granule for bouncing on and along an inclined face by mechanical action, by introducing air flow and/or by predetermined height of air fall. The air flow is introduced at upper side of the inclined face in a housing (1) of a cleaning device. A suction channel (4) with a suction connection (5) is provided below the inclined face. Air, which is contaminated with powdered and/or fibrous impurity, is sucked using an air suction device (6). The individual granule is discharged over an outlet (7) into a storage container (8) at an end of the inclined face. An independent claim is also included for a cleaning device for removing powdered and/or fibrous impurity from plastic granules, comprising a pivotable infeed section.</p> |
