With the widespread use of electronic devices, the amount of discarded circuit boards is also increasing. Circuit boards contain a variety of precious metals and harmful substances. If they are not effectively recycled and processed, it will not only lead to a waste of resources, but also cause serious environmental pollution. Therefore, the research and application of circuit board recycling equipment are particularly important. Circuit board recycling equipment mainly includes disassembling equipment, crushing equipment, sorting equipment, and refining equipment, etc. Disassembling equipment is used to separate components and plastic shells on circuit boards; crushing equipment crushes circuit boards into small pieces for subsequent processing; sorting equipment separates metals and non-metals in circuit boards according to their characteristics; and refining equipment further purifies the recovered metals to improve their purity and quality. The application of circuit board recycling equipment not only reduces resource waste, but also reduces environmental pollution. By recycling metals and plastics from circuit boards, we can reduce the extraction and processing of primary resources, lower energy consumption, and reduce greenhouse gas emissions. At the same time, recycling equipment can also process harmful substances in circuit boards, reducing pollution to soil, water, and air. However, the research and application of circuit board recycling equipment still face some challenges. Firstly, the structure and composition of circuit boards are complex, and different types of circuit boards require different recycling processes and equipment, which increases the difficulty and cost of developing recycling equipment. Secondly, the automation and processing capacity of circuit board recycling equipment still need to be improved to meet the growing demand for circuit board recycling. In addition, the market promotion and application of circuit board recycling equipment also need to be further strengthened to raise people's awareness of environmental protection and resource recycling. Circuit board recycling equipment is the key to environmental protection and resource recycling. With the increasing awareness of environmental protection and the growing demand for resource recycling, the research and application of circuit board recycling equipment have broad prospects. We should strengthen the research and application of circuit board recycling equipment, improve the recycling utilization rate of circuit boards, reduce resource waste and environmental pollution, and contribute to building a beautiful China.
