Wire chopping is a process of chopping and separating. Chopping is done with three granulators and screens that hold the wire until its small enough to pass through. Once shredding the small pieces of copper and plastic (3.5-6mm) continue onto an air table. These two air tables using vibration and air will free the copper from plastics/aluminum. The copper is then pushed to sieve tables which separate the fine copper from the copper chops. The plastic and micro-fines are put into a HAMOS machine. HAMOS is a high voltage machine that gives an electrical charge to the remaining pieces of copper, in order to separate it.
