3D animation video of PCB(printed circuit board) recycling machine

PCB(printed circuit board) recycling machine is an environmental friendly machinery, which is designed for processing waste printed circuit boards to separate precious metals out of resin fiber through crushing and separating.

The detailed working process of PCB(printed circuit board) recycling machine as follows:

Shredding:

Firstly, using a double-shaft shredder to shred the waste circuit boards into small pieces, due to its large size and certain hardness, which cannot be directly processed.

Crushing:

From the 3D animation video of PCB(printed circuit board) recycling machine, we can see that there are two steps of crushing: The first crushing is hammerhead crushing, which is used to crush the small pieces into smaller pieces. The second crushing is hammer crushing, which is used for crushing the smaller pieces into small particles.

Between the two crushing, a magnetic separator will be used to remove the iron from the small pieces.

Sieving:

After crushing, there is an eddy-vibrating screen, which is used to control the size of particles. The eddy-vibrating screen has two layers and there is a screen inside it. If the size of particles is bigger than the screen, they will be sent back to the hammer crushing for further crushing until they can go through the screen. On the contrary, the smaller particles will go through the screen to the next step.

Air separation:

The gravity of metals and non-metals is different, air separator can separate the metals from non-metals according to the different gravity.

Electrostatic separation:

The last step of PCB(printed circuit board) recycling machine is electrostatic separation. Due to the several crushing, the gravity of metals and non-metals is similar, which can be separated clearly by air separation. Therefore, electrostatic separator is necessary. It can separate the metals from non-metals by taking advantages of the different conductivity of metals and non-metals in a closed high-voltage magnetic field.

Tips: if there are electronic components on the waste circuit boards, you can use a PCB dismantling machine to remove the electronic components firstly.
