Abstract

The extraneous materials (30, 32/34, 36 and 24) arising in waste paper dissolution, with the exception of heavy materials which cannot be further utilised, are collected and fed to one (40) or two series-connected treatment devices (40, 56). The extraneous materials are subjected to a first comminution (42) rendering them uniform, in order to convert them into a state conveyable in suspension, are then predisintegrated (46) and freed of heavy dirt (48), in order to be ultimately fine-comminuted and disintegrated in a second comminution stage (52). The treatment device (56) serves essentially for upstream coarse comminution of the ragger rope (24) which may also be used. The suspension of extraneous material, obtained in the discharge shaft, is divided by sorting into a fibre material component and a residue component, of which the residue component is freed of fractions of higher density, and the substantially remaining thermoplastics are dried and granulated for re-use as semi-finished product in plastics processing. The long-fibre material component obtained is beaten and sorted in the conventional manner and, during beating, regenerated thermoplastic material in a finely divided form can be added to the fibre material for its later use in raw papers for corrugated board. <IMAGE>
