How does a circuit board recycling equipment work?

As the name suggests, circuit board recycling equipment is a recycling machine to process waste circuit boards, such as waste computer mother boards, mobile boards, copper clad laminate, printed circuit boards, circuit board scraps, etc. Circuit board recycling equipment can separate precious metals from resin fiber through processing the waste circuit boards.

Well, how does circuit board recycling equipment work? The following working video can help us to have a better understanding of the working process of circuit board recycling equipment.

1. Shredding - the first working process of circuit board recycling equipment is shredding, which is used to process the big or thick waste circuit boards. Double-shaft shredder can shred these circuit boards into small pieces, which are easy to process.

2. Crushing - it is used to crush the small circuit board pieces into small particles. This step will use two crushers:hammerhead crusher and hammer crusher. Both of the crusher are made of good materials, like 65Mn, which has high wearness and hardness.

3. Eddy-vibrating sieving - eddy-vibrating screen is used to control the size of particles. There is a 26 mesh screen inside it, which can stop the bigger particles. The bigger particles will be sent back to hammer crusher for further crushing, until they can pass through the screen.

4. Air separation - air separator is used to separate crude metals from resin fiber, which adopts the different gravity of metals and resin fiber. The separating rate can reach to about 98%.

5. Electrostatic separation - the last step of circuit board recycling equipment will separate fine metals from the resin fiber. Due to the two crushing, the gravity of some metals and resin fiber is similar, which can't be separated from resin fiber. Electrostatic separator is used to separate fine metals from resin fiber according to the conductivity of metals. The separating rate can reach to 99%.

Electronic components dismantling machine

Besides, in order to get purer metals, the electronic components can be removed first. Electronic components dismantling machine can dismantle the electronic components from waste circuit boards, using the property that metal tin will melt at high temperature and the firction between the circuit boards.

During the whole process, the cyclone and pulse dust collector will capture the dust with the collecting rate of 99.5% to make your site clean. Moreover, it uses no water, fire or chemicals, it is an environmental friendly machine.
