Most waste PCB recycling companies directly break the entire board, mixing high-value components with substrates, greatly increasing the difficulty of subsequent sorting.
Renewable independently develops a component disassembly machine that uses thermal assisted desoldering technology to completely and non destructively separate circuit boards and components, assisting in precious metal recovery, copper material purification, and stable operation of production lines.
Compared to traditional manual dismantling, the equipment only requires 2 people to operate continuously, significantly reducing labor costs; Equipped with a fully automatic temperature control system, it accurately controls the melting of solder and avoids metal oxidation losses caused by high temperatures.
For circuit boards equipped with high-value components such as CPUs, IC chips, gold-plated connectors, and surface mount capacitors, this process can maximize the preservation of component integrity and significantly improve the yield of precious metal extraction.
PCB substrates and components belong to two types of recycled materials:
The main components of the substrate are copper, fiberglass, and epoxy resin;
Components are enriched in precious metals such as gold, silver, palladium, copper, and nickel.
Industry data shows that the gold content of high-end components is much higher than that of bare boards. Direct crushing will dilute precious metals and increase sorting and smelting costs.
After pre-processing by the equipment, the materials are divided into two categories: bare PCB boards and disassembled components, which are disposed of separately:
After crushing and grinding, the bare board is subjected to air and electrostatic sorting, which improves the homogeneity of the material and achieves a copper powder purity of over 95% -98%;
Remove the components and extract precious metals separately, avoiding dilution of precious metals and significantly improving the overall metal recovery rate.
For electronic waste plants with an annual processing capacity of over 500 tons, the use of pre dismantling technology can quickly recover equipment investment costs.
The components contain ceramic, metal, and irregular plastic structures, and direct crushing will exacerbate tool wear, increase the load on the crusher, frequently replace the screen mesh, and disrupt the stability of the sorting system. Pre dismantling reduces the impact on downstream equipment and ensures the long-term stable operation of the entire production line.
The equipment integrates an exhaust gas purification device to collect and process the smoke generated by heating in a unified manner. Compared with open thermal dismantling, it effectively suppresses the leakage of smoke and harmful exhaust gas, which meets the environmental protection standards for electronic waste recycling.
Ultra short and streamlined version (suitable for poster and short video copywriting)
Conventional PCB boards are prone to mixing with precious metal components, resulting in high sorting costs. The Renewable Component Dismantling Machine adopts thermal desoldering separation technology to non destructively disassemble high-value components such as circuit boards, chips, and gold-plated parts.
Only two people are needed for continuous production, with intelligent constant temperature to prevent metal oxidation; Bare board and component diversion processing, copper powder purity of 95% -98%, significantly improved precious metal recovery rate, and short payback period for enterprises with a production capacity of over 500 tons.
