The working process of the waste refrigerator recycling line is to transport the manually processed waste refrigerators to the shredder for primary crushing, and then enter the hammer crusher for secondary crushing. At the same time, part of the polyurethane foam separated by winnowing will enter the foam separator. The crushed plastic and metal materials go through magnetic separation and iron separation on the belt, and then enter the eddy current separation. Non-ferrous metals such as copper and aluminum are separated by eddy current, and plastics and foam materials are transported to the air separation system through belts to separate pure plastics and foams.
