Abrégé

A method for processing, namely recycling, a workpiece made of electroplated plastic. In which method a coating is removed from the workpiece by a fragmentation unit by applying the electrohydraulic effect to a suspension containing plastic granules and containing coating granules. The suspension is dewatered, and a magnetic separator is used to separate the plastic granules from the coating granules by means of magnetic separation.

Abrégé

The invention relates to a method for breaking down and comminuting a product by means of the electrohydraulic effect, in which, in a container (4) filled with a liquid, a discharge with a pulse energy or discharge energy less than 100 J, preferably between 1 J and 50 J, particularly preferably between J and 20 J, is generated substantially in the liquid by means of a pulse current source (SQ) within an underwater spark gap between at least one first electrode (9), in particular mass electrode, and a second electrode (10), in particular high-voltage electrode, the product to be comminuted lying in the spark gap in the continuous or discontinuous container (4). The invention also relates to a device (2) for breaking down and comminuting a product.
