In today's era of rapid technological development, electronic products are updated and replaced at a rapid pace, and the number of circuit boards, as the core components of electronic products, is also increasing rapidly. However, these circuit boards contain a large amount of precious metals and harmful substances. If they are discarded indiscriminately, it will not only cause serious pollution to the environment, but also result in a great waste of resources. Therefore, circuit board recycling equipment has emerged as the key in the field of environmental protection and resource recycling. Circuit board recycling equipment mainly includes disassembling equipment, crushing equipment, sorting equipment, and refining equipment, etc. The disassembling equipment is used to separate the components and plastic shells on the circuit board, while the crushing equipment crushes the circuit board into fine particles. The sorting equipment can sort the metals, plastics, glass, and other substances in the circuit board according to their different physical and chemical properties. The refining equipment can refine and process the recovered metals, making them reusable resources. The application of circuit board recycling equipment can not only effectively reduce the pollution of circuit boards to the environment, but also recycle the precious metals and other useful resources in them, realizing the recycling and utilization of resources. According to statistics, each ton of circuit boards recycled can extract about 300 grams of gold, 1,000 grams of silver, 100 kilograms of copper, and other rare metals. The value of these resources far exceeds the value of the circuit boards themselves. However, at present, the application of circuit board recycling equipment in China still faces some problems. On the one hand, due to the high investment cost of circuit board recycling equipment, some small circuit board recycling enterprises find it difficult to afford, resulting in a low popularity of circuit board recycling equipment. On the other hand, due to the imperfect supervision of the circuit board recycling industry, some criminals, in order to seek profits, directly transport unprocessed circuit boards abroad or mix them into household waste for incineration and landfill, causing serious pollution to the environment. In order to solve these problems, the government and enterprises should strengthen cooperation and increase the research and promotion of circuit board recycling equipment, reduce the investment cost of equipment and increase the popularity of equipment. At the same time, the government should strengthen the supervision of the circuit board recycling industry, improve relevant laws and regulations, and severely crack down on the illegal activities of criminals to ensure the healthy development of the circuit board recycling industry. Circuit board recycling equipment is the key in the field of environmental protection and resource recycling. Its application can not only effectively reduce the pollution of circuit boards to the environment, but also recycle the precious metals and other useful resources in them, realizing the recycling and utilization of resources. We should strengthen the research and promotion of circuit board recycling equipment, improve relevant laws and regulations, ensure the healthy development of the circuit board recycling industry, and contribute to the construction of a beautiful China.
