2019-12-10 By Suny Group

With the acceleration of the updating speed of electronic products, the number of discarded printed circuit boards (PCBs), which are the main components of electronic waste, is also increasing. Environmental pollution caused by waste PCBs has also caused concern in various countries. On the waste circuit boards, there are nearly 20 kinds of nonferrous metals and rare metals, which have high recycling value and economic value.

Circuit board recycling and reuse methods are physically broken and environmental pollution is small. After physical and mechanical processing, including crushing and sorting. The waste circuit board is first crushed by the coarse crusher and then crushed by the fine crusher, and then sorted by the magnetic separator to separate the ferromagnetic materials. After that, the electrostatic separation is used to achieve the separation accuracy. Secondary pollution.

E-waste usually contains a large amount of toxic substances such as lead, chromium, mercury, etc., which causes great pollution and widespread harm. Improper disposal will not only cause waste of resources, but also cause great environmental pollution and even directly threaten human health. After professional recovery, through the special treatment such as "breaking-dismantling-sorting", renewable resources such as copper, aluminum, plastic, and rare precious metals can be separated, with great economic value.
