PCB board recycling machine
PCB board recycling machine can directly and easily auto-disassemble the motherboard, making its circuit boards and electronic components to achieve perfect separation, in order to the next recycling, this high quality PCB board recycling plant has a power-saving, easy operation and high efficiency advantages.After dismantling, the scrap motherboard is divided into printed circuit board and lots of electronic components.
How to extraction copper from waste pcb board?
PCB board recycling machine working process
1.Generally, it goes first crusher, second crusher, air separator,high electrostatic separator,or gravity separator, you can also get different metals separately, such as: copper, tin, and other precious metals (gold, silver, etc.) from our mixing metals.
2.Because of the special physical characteristics of E-waste circuit boards, our equipment are adopt the dry-type grinding and separating technique to recycle and reuse.
3.The printed circuit boards will be separated into metal powder and resin fiber powder. First, the waste circuit boards will be crushed into small pieces, then will be grinded into the powder mixture of metal and resin fiber. The mixture will be completely separated via pulse air flow separation to get 97% mixed metal powder.
4.Finally, the rest mixture powder will go into the high voltage electrostatic separator, the purity can be up to 99.9%, and the impulse dust catcher is approached to efficiently prevent the dust pollution.
