Circuit board crushing and recycling equipment introduction:

1. Shredder: Shred the light board to 2-3 cm.

2. Circuit board crusher: crush the crushed circuit board to about 20 mesh.

3. Analyzer: the crushed material is air sorted, resin, copper, dust, and fiber are separated. The dust and fiber are sucked into the collector by the induced draft fan, and the resin and copper enter the grading sieve.

4. Collector: Collect dust and fibers, and discharge the collected fibers.

5. Pulse purifier: collect the dust and superfine fibers generated in the crushing process.

6. Classification screen: screen the resin and copper. The resin and copper that are not separated are returned to the main machine and then pulverized. The separated resin and copper enter the specific gravity separator for separation.

7. Specific gravity sorting: resin powder and copper are sorted by specific gravity. Since the weight of copper is greater than the weight of resin, copper will be sorted to one side, and resin will be sorted to the other side. In this way, the separation of metal and non-metal is achieved.

8. High-voltage electrostatic sorting: the tailings that have passed through the specific gravity sorting machine are subjected to high-voltage electrostatic sorting to separate the small copper powder contained in the tailings from the resin

Discarded circuit boards are multiphase and relatively high in complexity. For integrated waste circuit boards, the complexity is greater. Therefore, they are allowed to be separated into separate parts for recycling.
