Is PCB Circuit Board Recycling Profitable?

With the dramatic increase in electronic waste, precious metals such as copper, gold, and silver within discarded circuit boards can be recovered and reused, yielding significant economic benefits. The PCB circuit board recycling machine serves as a vital piece of equipment for the resource recovery of electronic waste. It is specifically designed to process materials such as discarded circuit boards, copper-clad laminates, and electronic component offcuts. This equipment efficiently separates components including copper, aluminium, gold, silver, resin powder, and glass fibre. It achieves the dual objectives of resource recycling and environmentally sound disposal, thereby assisting in resolving the challenges associated with electronic waste recovery and processing.

The circuit board recycling machine employs a process flow incorporating ‘multi-stage crushing + air classification’. First, a dedicated shredder breaks down PCB circuit boards into small pieces. These are then refined to millimetre-sized particles using water-cooled or air-cooled crushers, ensuring thorough separation of metals and non-metallic waste. Subsequent preliminary screening is conducted using a gravity separation screen, followed by a dual-stage separation process utilising high-pressure magnetic separation. This precisely separates materials based on density and conductivity differences. The entire production line achieves a metal recovery rate exceeding 98%, with copper purity surpassing 96%. Even minute precious metal particles are fully recovered.

Regarding environmental performance, the system operates under continuous negative pressure with pulse dust removal, achieving 99.9% dust recovery. No wastewater or exhaust gases are produced. The production line is suitable for recycling various circuit board types: mobile phone boards, computer motherboards, electronic control boards, television motherboards, etc. The circuit board recycling machine is equipped with a PLC intelligent control system, enabling fully automated operation.

Widely deployed in electronic waste processing plants, precious metal recovery enterprises, and resource regeneration facilities, the circuit board recycling machine provides an integrated solution for the economic, efficient, and environmentally sound recycling of waste circuit boards.
