What is the PCB board recycling process?

Are you curious about how dose the PCB board recycle by the PCB board recycling machine? What is the PCB board recycling process? Don't be hurried. The following passage will provide details about what is the PCB board recycling process.

PCB board recycling machine

Henan Doing Environmental Protection Technology Co., Ltd 's PCB board recycling machine is specially designed for processing PCB board. It is very easy to operate. The whole process including dismantling, shredding, crushing, sieving and separation 5 steps.

Step 1: Dismantling

Normally, there are various electronic components on the PCB boards. These components are usually made of various cheap metals, which will affect the final mixed metals quality. Therefore, we will recommend you to dismantle the electronic components from the PCB boards first. By using the principle of heating, the PCB board dismantling machine will dismantle electronic components from the board. Finally, you will get electronic components and bare board.

Step 2: Shredding

Because the bare board is too big to process, we should process its size firstly. The shredder will shredd the bare board into small pieces.

Step 3: Crushing

This step contains two times hammer crushing. And after the two hammer crushing, the small pieces will become small particles, which will be easier to be separated.

Step 4:Sieving

Eddy-vibrating screen is used to control the size of particles. If some particles is bigger than the screen, these particles will be sent back to the crusher to further crushing. The small particles will flow into the next step.

Step 5: Separation

This step will use the air separator an electrostatic separator. The air separator will separate metals and non-metals according to their different gravities, well the electrostatic separator adopts the principle of different conductivies of different objects in the magnetic field. Under the processing of air separator and electrostatic separator, the separation rate of metals and non-metals can reach to 99%.

The process adopts dry type physical separation way to separate metals and non-metals, which will not emission waste water and toxic chemical to the environment. Besides, the dust generate during the process will be collected by the pulse dust removal system, which will not produce waste air to the environment. The whole process is a totally environmental friendly process.
