How does PCB recycling machine work?

There are many metals, like copper, silver, tin, palladium, chrome, etc. inside waste circuit boards. PCB recycling machine is used to separate these precious metals from the waste circuit boards. Well, how does PCB recycling machine works?

To gain a comprehensive understanding of the working process of PCB recycling machine, let us delve into its intricate working process, as elucidated by a demonstrative video.

1. Shredding

The initial stage of the working process uses a double-shaft shredder. Shredder is tasked with reducing large or thick waste circuit boards into small fragments.

2. Crushing

Following the shredding phase, a hammerhead crusher and hammer crusher will be used to process the small fragments, to crush them into smaller particles. The hammer crusher is made of wear-resistant and highly durable 65Mn steel, which can effective crush waste circuit boards fragments.

3. Eddy-Vibrating Sieving

The crushed materials will enter an eddy-vibrating screen, which is used be to control the particle size. Fitted with a 26mesh screen, eddy-vibrating screen can prevent the oversized particles from entering the next step. The bigger particles will be returned to the hammer crusher for further processing until they successfully meet the required particle size criteria.

4. Air Separation

Subsequently, an air separator takes center stage in the process, exploiting the distinct gravity of metals and resin fibers. Through this advanced technique, crude metals are effectively segregated from the resinous component, achieving an impressive separation rate of approximately 98%.

5. Electrostatic Separation

Since some materials are completely broken, the gravity of some metals may be similar to that of resin fibers, and air separation cannot separate them clearly. Therefore, electrostatic separator is used to separate metals in resin fibers, according to their different conductivity. The separation rate can reach to 99%.

6. Electronic Components Dismantling

In pursuit of even higher metal purity, an electronic components dismantling machine can be used to remove the electronic components. Harnessing the unique property of metal tin, which melts at elevated temperatures, along with the frictional forces exerted on the circuit boards, this auxiliary equipment efficiently removes electronic components from the waste stream prior to the main recycling process.

7. Dust Collecting

Throughout the entire recycling operation, a cyclone and a pulse dust collector can collect the dust with the efficiency of 99.5%, ensuring a clean and safe working environment.
