Abstract
A method of recycling scrap is disclosed, comprising the steps of shredding the scrap with a shredder into shredded scrap objects, classifying the shredded scrap objects into fractions of scrap objects having different size ranges with a classifier, and sorting scrap objects while substantially maintaining interspace between the objects. Further, a singulating arrangement for singulating scrap objects is disclosed, comprising a substantially horizontally disposed feeder that extends from a receiving area for receiving scrap objects to a feed gate positioned at a top portion of a chute, as well as an ejector arrangement, comprising a conveyor with a substantially flat conveying plane and an ejector device disposed along the conveyor.
Claims19
A method of recycling scrap, comprising the steps of—
- shredding the scrap with a shredder into shredded scrap objects, the scrap being shredded to include objects having maximum pass through dimensions in the range of 50-200 mm,
- classifying the shredded scrap objects into fractions of scrap objects having different size ranges with a classifier, at least one size range including objects having maximum pass through dimensions in the range of 50-200 mm, and
- sorting scrap objects from at least one size range that includes objects having maximum pass through dimensions in the range of 50-200 mm, while substantially maintaining interspace between the objects.
A system for recycling scrap comprising a shredder for shredding scrap into shredded scrap objects and a classifier for classifying the shredded scrap objects into fractions of scrap objects having different size ranges, at least one of said size ranges including objects having maximum pass through dimensions in the range of 50-200 mm, the system further comprising a sorter arranged to sort objects from said at least one size range that includes objects having maximum pass through dimensions in the range of 50-200 mm, while substantially maintaining interspace between the objects.
