Recycling Revolution of Waste Circuit Boards: Circuit Board Recycling and Processing Equipment Embarks on the Golden Age of Urban Mines
The gold content of a discarded mobile phone circuit board can reach 280 grams per ton, nearly a hundred times that of natural gold mines, and it also contains dozens of valuable metals such as copper, tin, palladium, and silver. However, among the over 53 million tons of electronic waste worldwide each year, the formal recycling rate of circuit boards is less than 20%, and a large amount flows into illegal dismantling channels, causing serious pollution through acid leaching and incineration. Waste circuit boards are not garbage, they are strategic resources that have been misplaced. Technological breakthrough: from extensive disassembly to precise sorting Modern circuit board recycling and processing equipment adopts physical methods for full process automation, achieving clean production with zero wastewater and zero exhaust gas Crushing and dissociation : Dual axis shredding+ultrafine crushing, allowing metals and non metals to fully dissociate -Multi level sorting: airflow sorting+electrostatic sorting+specific gravity sorting, copper recovery rate ≥ 99% Environmental protection treatment : three-level dust removal and purification, with particle emissions below 10mg/m ³ Double leap in efficiency and effectiveness Taking a medium-sized production line with a capacity of 1 ton per hour as an example, it can process approximately 7200 tons annually,...
