How do you remove metals from printed circuit boards?

The proportion of metal in the waste circuit board accounts for 40%, like copper, gold and so on. Some metals can be recycled, and the price is pretty high. So throw waste circuit board away directly is unwise. Today I will introduce a machine to separate metals from circuit board, called PCB board recycling machine.

PCB board recycling machine could remove metals from printed circuit board. DOING PCB board recycling machine is an environmental friendly equipment which is special designed for separating metals from non-metal. The main process of PCB board recycling machine including shredding, crushing, sieving, air separation and electrostatic separation. Through the 5 steps, you will get metals from circuit board.

But before using PCB board recycling machine, you should need a PCB dismantling machine to separate electronic components from circuit board.

The main process of PCB board recycling machine as follows:

Main process of PCB board recycling machine

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.

Furthermore, the PCB board recycling machine is completely physical separation during the whole working process, so there will be no pollution. The separated metals and resin fiber can be sold on the market or used for producing new products. Compared to traditional methods, remove metals from circuit boards with PCB board recycling machine will not only guarantees high separation rate, but also does not pollute the environment.

DOING is a manufacturer of PCB board recycling machine. DOING has been engaged in the production of metal recycling equipment for more than ten years. It has rich experience in waste recycling. So later if you have any interest about PCB board recycling machine, just feel free to contact us DOING!
