Method and device for separating metal / plastic composites, preferably boards, for the recycling of old electrical appliances

摘要

A method for separating metal / plastic composites, preferably circuit boards, for the material recycling of old electrical devices is shown and described. So that metal / plastic composites, which essentially represent circuit boards, circuit board fragments and comparable objects, can be separated with a reasonable amount of effort and at the same time with a high degree of purity, the steps mechanical shredding of the old electrical devices, separation of the shredded old electrical devices into a metal part and the metal Metal fraction containing / plastic composites and a non-metal fraction, feeding the metal fraction to an optoelectronic sensor module, detecting the metal / plastic composites in the metal fraction and separating the identified metal / plastic composites from the metal fraction is proposed.
