PCB and Copper Clad Laminate Recycling Machine for Crushing and Copper Separation

For efficient printed circuit board recycling, the raw material condition is critical. Industrial processes recommend dismantling motherboards over assembled ones, as removing electronic components before crushing stabilizes feeding and prevents large solder joints, capacitors, and connectors from disrupting particle size distribution. This step also reduces crushing equipment wear and aids later separation of metal and non-metal fractions.

This PCB recycling machine is developed for treating waste circuit boards, copper-clad laminates, printed circuit board offcuts, and production scrap after components have been removed. In addition to reducing material size, the machine increases profits for recyclers by releasing copper from resin-based substrates, enabling separate recovery of conductive metals and non-conductive materials. As a result, both copper and resin powder become marketable outputs, reducing waste and improving resource efficiency.

How the Separation Process Creates Recoverable Output
The separation process follows a three-stage crushing route. A double-shaft shredder first reduces large boards into manageable pieces, then a hammer crusher breaks the material further, and finally a high-speed turbine grinder converts it into 40–80 mesh mixed powder. After repeated crushing, copper particles, resin powder, and fiber detach more completely from each other, which directly improves sorting precision in the next stage.

Once grinding is completed, the material passes through air separation and electrostatic separation. Airflow removes lighter resin powder first, while conductive metals move into high-voltage electrostatic sorting, where copper and other metallic fractions are separated from non-conductive material. Under stable operating conditions, the metal recovery rate can reach up to 99%, making this waste circuit board recycling machine suitable for recyclers who need high copper purity together with consistent resin recovery.

To keep output stable during continuous operation, the line also integrates negative-pressure conveying, pulse dust collection, and circulating water cooling. Dust remains inside the system instead of escaping into the workshop, while the grinder temperature stays controlled during long working hours. The full PCB crushing and sorting recycling machine runs under PLC control, with regrinding for incompletely separated material, helping reduce copper loss and improve the real return from copper recovery from PCB processing. For buyers evaluating PCB recycling equipment, utilizing pre-dismantled circuit boards as raw material enables the crushing and sorting system to operate with lower wear rates, fewer operational interruptions, and more stable copper recovery rates.
