The rational sorting and production process of electronic waste recycling and processing equipment involves: raw materials undergoing shredding, coarse crushing, pulverizing, airflow sorting, vibration separation, and environmental treatment. This allows for the recovery of a mixture of precious metals, primarily copper, and a mixture of non-metallic powders. Dust and waste gas generated during processing are collected systematically and treated with dust removal and waste gas purification, ensuring environmental compliance before being discharged into the atmosphere.
Electronic waste materials such as circuit boards, computer boards, television boards, mobile phone boards, copper-clad laminates, and other metal-containing electronic waste from dismantled household appliances contain not only common metals such as aluminum, copper, iron, nickel, lead, tin, and zinc, but also precious and rare metals such as gold, palladium, platinum, and silver. This not only allows for high resource utilization but also effectively solves environmental pollution problems through physical recycling methods, possessing significant green economic value.
