What is the full process of recycling circuit boards?
Recycling of scrap circuit boards is an important environmental task that involves multiple stages and related equipment. The following is an introduction to the typical full process of recycling scrap circuit boards:
Collection and classification: First, scrap circuit boards need to be collected and classified according to different types. This includes waste circuit boards obtained from dismantling electronic equipment, communication equipment, computers, etc.
Circuit Board Disassembly: In this stage, a circuit board disassembly machine is used to disassemble the circuit board and separate it from other components using specialized equipment. This usually involves removing components, sockets, metal parts, etc. from the circuit board. After disassembly, the circuit board needs to be cleaned to remove dust, oil, and other contaminants.
Crushing and pulverizing: The disassembled circuit board motherboard is processed by crushing and pulverizing equipment to convert it into smaller powder materials. This facilitates subsequent processing steps.
Physical separation: Use physical separation equipment, such as electrostatic separators, gravity separators, etc., to separate circuit board particles according to density, size and other characteristics. This can separate metal and non-metal parts such as copper, aluminum, plastic, etc.
Chemical Treatment (Precious Metal Recycling): In some cases, chemical treatment is required to remove harmful substances from circuit boards. For example, removing contaminants from metal surfaces through a pickling process, or using chemical methods to extract valuable metal elements.
Regeneration and recycling: Separated and processed materials can be further regenerated and recycled. Metal parts, such as copper and aluminum, can be smelted and refined to produce pure metals for use in the production of new electronic products. Plastic parts can be recycled and used to make new plastic products.
Related equipment includes but is not limited to:
Circuit board disassembly equipment: used to separate circuit boards from other components and clean the circuit board surface.
Crushing and pulverizing equipment: Breaks circuit boards into smaller particles or powder.
Physical sorting equipment: such as electrostatic separators, gravity separators, etc., used to separate metal and non-metal parts according to material properties.
Chemical treatment (precious metal recycling) equipment: used to remove harmful substances from circuit boards, such as pickling equipment, and to recover precious metals in disassembled components, such as gold, silver, palladium, etc.
Regeneration equipment: including smelting furnaces, refining equipment, etc., used to regenerate metal parts.
Plastic recycling equipment: used to recycle plastic parts, such as plastic crushers, plastic granulators, etc.
The entire process of scrapped circuit board recycling involves multiple links and equipment, and each link is crucial to environmental protection and resource recovery.
