How to recycle waste circuit boards

At present, the recycling and treatment of waste circuit boards generally adopt methods such as direct burial, incineration, water washing and cracking, but there will be release of toxic substances, which will easily cause serious secondary pollution of the air or soil, and the national environmental protection policy does not allow of. The best way to promote the recycling of waste circuit boards in the world is to use waste circuit board recycling equipment and circuit board recycling and resource utilization equipment. These circuit board separation and recycling (circuit board separation and recycling) are suitable for various circuit boards, circuit boards, Recycling of electronic waste such as FPC flexible circuit boards. It has the advantages of low environmental pollution, high comprehensive utilization rate, and large added value.

Production Process

Waste circuit boards and circuit boards are put into the entrance of waste circuit board recycling equipment, and directly enter the production line for processing and production. Waste circuit boards are detinned after initial treatment.

The circuit board after de-tinning enters the crusher for coarse crushing and magnetic separation, and the magnetic substances can be sorted out and collected, and then the magnetic substances can be recycled and collected.

The coarsely crushed material is crushed again after removing the magnetic material, and the fine powder is recovered through the dust collection equipment. There is an exhaust gas treatment device in this link. The fan can let the exhaust gas pass out.

The materials that do not contain fine powder after being crushed again are screened. Part of the specific gravity sorting equipment is used to obtain metal substances. metal substance.

After the waste circuit boards pass through the waste circuit board recycling equipment, tin, magnetic substances, fine powder, metals, and non-metallic particles are sorted out, and these substances can be recycled and reused.
