With the widespread use of electronic devices, circuit boards have become an important component of e-waste. These circuit boards contain a large amount of precious metals and harmful substances. If they are not properly disposed of, they will have a serious impact on the environment and human health. Therefore, the development and application of circuit board recycling equipment have become 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 casings on circuit boards. Crushing equipment crushes circuit boards into small pieces. Sorting equipment can separate components according to their different characteristics, and refining equipment is used to refine and purify the recovered precious metals. The application of circuit board recycling equipment not only reduces the pollution of e-waste to the environment, but also saves resources and reduces production costs. By recycling precious metals such as gold, silver, and copper from circuit boards, we can achieve the reuse of resources and reduce the exploitation and consumption of natural resources. At the same time, the application of circuit board recycling equipment can also reduce the production costs of enterprises and improve their economic benefits. However, the development and application of circuit board recycling equipment still face some challenges. Firstly, the types and structures of circuit boards are very complex, and different circuit boards require different recycling processes and equipment, which increases the difficulty of developing circuit board recycling equipment. Secondly, the cost of circuit board recycling equipment is relatively high, and a large amount of funds and technical forces are needed for research and development and production, which also limits the widespread application of circuit board recycling equipment. Circuit board recycling equipment is a key force in e-waste processing, and its development and application are of great significance for protecting the environment, saving resources, and reducing production costs. Although the development and application of circuit board recycling equipment still face some challenges, with the continuous progress of technology and the increasing awareness of environmental protection, it is believed that circuit board recycling equipment will be more widely used in the future.
