Problems solved by technology
[0003] However, most of the traditional circuit board recycling relies on chemical recycling, which has high recycling costs and will pollute the environment. At the same time, the resin material is easy to adhere to the metal material, and the separation is not complete, resulting in a low metal recovery rate and causing metal resources. waste

Description
technical field [0001] The invention relates to the technical field of recycling circuit boards, in particular to a device for recycling metal scraps of waste circuit boards. Background technique [0002] Waste circuit boards are made of a mixture of resin and various metals. Waste circuit boards are rich in various valuable metals (such as copper, lead, zinc) and waste metals (such as gold, silver, rhodium). The metal content in ordinary minerals is several times or even dozens of times higher than that in ordinary minerals. Considering the utilization value of metals, it is necessary to collect metals on discarded circuit boards, which requires the collection and classification of resin materials and various metals. [0003] However, most of the traditional circuit board recycling relies on chemical methods for recycling, which has high recycling costs and will pollute the environment. At the same time, it is easy to make resin materials adhere to metal materials, and the ...
