With the rapid development of technology, electronic waste is growing at a rate of 53 million tons per year, with circuit boards being the most valuable for recycling. Research on ordinary circuit boards shows that the proportion of electronic components is 58%, the proportion of baseboards is 37%, and the proportion of solder is 5%. It is estimated that 1 ton of computer circuit board contains 0.5 kg of gold, 130 kg of copper, 10 kg of iron, 60 kg of lead, 40 kg of tin, 36 kg of nickel, 40 kg of antimony, as well as some other rare and precious metals such as platinum and palladium. Due to the high value of metals, fibers, and resins, they have high recycling value. Efficient electronic waste recycling equipment has become crucial.
The electronic waste recycling production line produced by Henan Renewable has a complete electronic waste recycling process, high degree of automation throughout the process, and high recycling efficiency.
Equipment process flow: The first stage crusher adopts a dual axis shredder, the second stage crusher adopts a hammer crusher, and the third stage crusher adopts a high-speed turbine crusher. The material is crushed into powder through three-stage crushing, and then sorted by air flow sorting equipment and electrostatic sorting equipment. This production line has high production capacity and low power consumption; One feeding, multiple machines collaborate to complete; The entire production line is controlled by PLC. The successful development of this machine not only improves the quality of copper recycling, but also prevents secondary pollution. Adopting pulse dust removal equipment, the dust removal efficiency is over 99%, effectively suppressing dust volatilization and fully complying with the national environmental protection requirements of the Comprehensive Emission Standards for Air Pollutants.
