Beschreibung
Zusammenfassung:	The invention discloses a waste PCB (printed circuit board) crushing and sorting system. The waste PCB crushing and sorting system comprises a disassembling unit, a crushing unit, a primary air classification unit, a deferrization unit, a grinding unit, a fine deferrization unit, an air classification separating unit, a high-voltage electrostatic separation unit, a dust and waste gas disposition unit and a central control unit, wherein a circuit board is disassembled and crushed, and then is subjected to procedures such as primary air classification, primary deferrization, grinding, secondary deferrization, air classification separating and high-voltage electrostatic separation, and a copper-containing metal concentration with the purity of 99.5% is obtained. The waste PCB crushing and sorting system provided by the invention is used for recovering available resources in a waste PCB plate treating process, treating the waste PCBs in scales, efficiently recovers resources, and avoids the environment pollution.
