<p>The invention relates to a method for the computer-controlled recovery of pure fractions of plastics from mixtures comprising to a large extent plastics parts, in particular packaging materials. The following process steps are provided for this: Coarse screening, fine screening, separation of film from the medium and coarse fraction, magnetic separation from the medium and fine fraction, separation of non-ferrous metals from the medium and fine fraction, ballistic screening of the medium fraction, isolation of the medium fraction, registering the size of the parts in the medium fraction by optoelectrical means, spectral analysis of the parts and computer-controlled discharge of the parts of the same or different grade. <IMAGE></p> |
