METHOD AND DEVICE FOR CLASSIFYING VALUABLE MATERIAL COMPRISING AT LEAST ONE FIBROUS FRACTION

Document Type and Number:

WIPO Patent Application WO2003010371

Kind Code:

A3

Abstract:

The invention relates to a method and a device for classifying valuable materials consisting of a viscoplastic fraction, particularly PE and PP films, and a fibrous fraction, particularly cellulose fibres, which enable an almost complete separation into cellulose fibres and plastics. To this end, the valuable materials are whirled up in the direction of a sieve (103) and the fibrous fraction is sucked through the same (103).
