The PCB board recycling machine is a special equipment for processing waste PCB boards, such as waste circuit boards, copper clad laminates, computer boards, various used electrical motherboards and so on. It can separate precious metals and resin fibers from these raw materials.
Before using the PCB board recycling machine, the PCB dismantling machine should be used to heat the tin so that the electronic components can be removed from the circuit board.
The process of PCB board recycling machine as follows:
1, Shredding
Put the circuit board in the shredder and cut it into small pieces.
2. Crushing
This step can make the small pieces smaller, making it easy to use a magnetic separator to remove iron. Iron removal can improve the working efficiency of the PCB board recycling machine.
3. Sieving
Smaller pieces can flow into the next step through the eddy-vibrating screen. The larger will flow back to the previous step and continue crushing.
4. Air separation
These smaller pieces will be sent to the air separator for air separation. The air separator separates them into metals and mixture of resin fibers and metals according to their different specific gravities.
5. Electrostatic separation
The last step is electrostatic separation. It separates them according to their different reactions in the magnetic field. Then, you can get metal and resin fibers.
Besides, we have the pulse dust removal system to clean the dust during the whole process. This is the whole process of the PCB board recycling machine. Through this process, you can obtain a purity of up to 99% metals and resin fibers. The higher the purity you get, the more profit you get.
