Electronic waste, particularly discarded computer circuit boards (PCBs), contains high-value components such as copper, tin, gold, silver, and resin. A complete PCB recycling technology solution can achieve efficient recycling through mechanical and physical sorting methods.

The high-efficiency crushing system is the starting point for recycling. Computer motherboards, graphics cards, circuit boards, etc., are automatically fed into the crusher via a conveyor system. The multi-stage hammer crushing structure gradually pulverizes the PCBs to a uniform particle size, creating a more ideal particle shape for subsequent sorting. Compared to single-stage crushing, multi-stage crushing significantly reduces dust generation, and the metal particles are more regularly shaped, which is beneficial for revealing differences in metal conductivity. If higher fineness is required, a fine-grinding system can be added to grind the material to 60-120 mesh, improving the separation of metals and non-metals. The entire crushing process operates in a closed loop and can be combined with a pulse dust collector to ensure stable and compliant dust emissions.

The crushed mixture then enters the electrostatic separation system, which is the core technology of the entire solution. PCB metals are highly conductive, while resin and glass fiber are non-conductive. Utilizing this difference, electrostatic separators can precisely separate metal powders into individual finished products, enabling the recovery of copper, tin, and other metal resources without chemical solvents. For higher purity, secondary electrostatic separation or gravity separation can be used for further purification, ensuring a stable copper recovery rate of over 98%. The recovered resin powder can be used in board materials, building materials, or fillers, forming a reusable closed loop. For larger production lines, high-frequency eddy current separators can be added to recover residual conductive particles, improving overall resource utilization.

For recycling plants with higher production demands, automated feeding and stable output can be achieved, equipped with water-cooling or air-cooling systems to maintain stable power output even during long-term operation. The entire PCB recycling line can be customized, including crushing capacity, sorting accuracy, dust removal systems, and finished product output methods, suitable for various scenarios such as electronic waste recycling companies, environmental resource regeneration plants, and metal sorting and processing lines. Whether processing old computer mainframes, TV boards, communication equipment boards, or upgrading large-scale recycling plant production lines, it can be quickly deployed and achieve stable profitability.
