Abstract

To sort used paper, a coarse sieve (6) separates cardboard and a fine sieve drum (8) separates impurities. The remaining used paper is carried on a high speed belt for wind sifting, as it is, and only the paper blown out is used for further processing while the heavier material is gathered for special treatment. The blown-out paper is caught by a suction hood (12) to be passed into the entry (20) of a zigzag sifter (21), where a counter air flow is blown through. The air flow is set so that the lighter paper material is blown upward through the outlet (24) to be gathered as paper where ink can be removed. The paper taken from the bottom of the zigzag sifter is passed to the entry (30) at a second zigzag sifter (31), and the lighter material taken from the upper outlet is returned to the entry of the first sifter, and the remainder is taken as mixed paper from the lower outlet (32).
