Abstract

A method for separating mixed paper qualities, especially laminated products such as corrugated cardboards, comprises preconditioning the product with a solvent, e.g. water, to mollify the adhesive bond. The preconditioned laminate is exposed in a mill to procure delamination and selective fragmentation of the constituent plies of the product. The mill (10) comprises an impeller (16) enclosed by a screen (26) through which paper fragments pass for collection, and a wiper (68) for unclogging the screen. <IMAGE>
