Circuit board recycling equipment facilitates e-waste recycling

The replacement of electronic products is very fast, and the elimination rate is also very high. Once electronic products are eliminated or discarded, they become useless “garbage”. Some people may not know that the metal grade in the circuit board is much higher than that of ordinary minerals. The metal content is as high as 40%, mostly copper, in addition to gold, aluminum, nickel, lead, silicon, etc. , and the metal content of my country’s rich ore is only 3 to 5%. Do people who call scrap circuit boards junk still call it junk?

Circuit board recycling equipment mainly processes various waste circuit boards, circuit boards, copper clad laminates, scraps, aluminum-plastic panels, waste medicine tablets, electronic components, etc.; circuit board recycling equipment can not only sort and separate metals from various metal wastes, but also The difficulty in the recycling of electronic waste – the recycling of waste printed circuit boards, also uses a combined process of crushing – magnetic separation – electrostatic separation to recover and extract metals from waste circuit boards.

The circuit board recycling production line is mainly composed of conveyor, primary crusher, secondary crusher, magnetic separator, pulverizer, sorting machine and other auxiliary devices. After the waste circuit boards are manually dismantled, the harmful electrical components such as batteries, transformers, etc. and reusable parts are removed, and the remaining parts are sent to the primary crusher by the scraper conveyor, and the materials are crushed to less than 20mm. Then it is sent to the secondary crusher to crush the material below 5mm, the iron-containing material is separated by the magnetic separator, and the remaining material is crushed to a powder of about 2mm by the crusher, so that the copper in the multi-layer machine board can be separated. The light dust is separated first by air separation, and the material with larger specific gravity is sent to the electrostatic separator to separate and recover about 20% of non-ferrous metals (copper, etc.).

Circuit board recycling equipment is the nemesis of electronic waste. Its appearance not only improves the quality of copper recycling, but also prevents secondary pollution of the environment. It is an ideal production line for recycling and separating waste circuit boards.
