How to extract copper and resin powder from scrap recycled pcb boards

Pubdate: 2022-09-16

The PCB board recycling machine can directly and easily disassemble the main board automatically, so that the circuit board and electronic components can be perfectly separated for the next recycling process. This high-quality PCB board recycling plant has the advantages of power saving, simple operation and high efficiency. After dismantling, the waste motherboard is divided into printed circuit boards and a large number of electronic components.
How to extract copper from waste pcb board?

  1. Generally divided into primary crusher, secondary crusher, air separator, high electrostatic separator, gravity separator, and different metals can also be obtained separately, such as: copper, solder and other precious metals (gold, silver, etc.) etc., requires additional environmentally friendly recycling line operations) from our mixed metals.
  2. Due to the special physical characteristics of electronic waste circuit boards, our equipment adopts dry grinding separation technology for recycling.
  3. The printed circuit board will be divided into metal powder and resin fiber powder. The waste circuit boards are first smashed into small pieces and then ground into a powder mixture of metal and resin fibers. The mixture was completely separated by pulsed gas flow separation, resulting in 97% mixed metal powder.
  4. The final remaining mixed powder enters the high-voltage electrostatic separator, the purity can reach 99.9%, and it is close to the pulse dust collector, which can effectively prevent dust pollution.
    In the end, we can get copper powder and resin powder to create economic value for the enterprises involved. The copper powder can be sold as copper ingots in the main city or sold to upstream and downstream enterprises, and the resin powder can be sold to furniture boards as fillers.
