Printed Circuit Board Recycling Process: High\u2011Purity PCB Recovery System<\/h2>\n

Waste printed circuit boards (PCBs) are abundant in computers, smartphones, appliances and other electronic products. Each board contains a mixture of metals\u2014copper, gold, silver and palladium\u2014and non\u2011metallic materials such as plastics and fiberglass. To capture these valuable resources, recycling must separate metals from resin and fiberglass without releasing hazardous emissions. Traditional thermal methods (incineration or smelting) can result in resource losses and pollution. Mechanical recycling\u2014combining shredding, crushing and physical separation\u2014achieves metal purities exceeding 99%, making it the preferred route for environmentally responsible PCB recycling.<\/p>\n

Overview of the PCB Recycling Process<\/h2>\n

The PCB recycling process typically follows three stages:<\/p>\n

    \n
  1. Dismantling:<\/strong> An electronic component dismantling machine removes chips, capacitors and other components from the board, leaving a bare circuit board for further processing.<\/li>\n
  2. Crushing & Pulverizing:<\/strong> The bare board is fed into a shredder or crusher to break it into 60 mm fragments. A granulator or hammer mill then reduces these fragments to particles around 20 mm. Mechanical crushing prepares the material for efficient separation.<\/li>\n
  3. Separation:<\/strong> A series of separation technologies\u2014magnetic, gravity, eddy current and electrostatic\u2014classify and concentrate the metals. High\u2011voltage electrostatic separators exploit differences in electrical conductivity to segregate metals from non\u2011metals with recovery rates over 99%.<\/li>\n<\/ol>\n
