Process flow of circuit board recovery equipment

Firstly, PCB is broken by mechanical means.The purpose of crushing is to make the metal in the waste circuit board dissociate from the organic matter as much as possible, so as to improve the separation efficiency.It was found that the metal could be almost 100% dissociated when broken at 0.6mm.The separation is realized by using the difference of physical properties such as density, particle size, electrical conductivity, magnetic conductivity and surface characteristics of materials.At present, the widely used technologies include wind shaker, flotation separation, cyclone separation, float and sink separation and eddy current separation.

E-waste is a valuable resource. It is of great significance to strengthen the research and application of e-waste metal recovery technology from both economic and environmental perspectives.Due to the complex and diverse characteristics of e-waste, it is difficult to recover the metals by any single technology. In the future, the development trend of e-waste treatment technology should be: industrialization of treatment forms, maximization of resource recovery, and scientific treatment technology.To sum up, studying the recycling of waste PCB can not only protect the environment and prevent pollution, but also facilitate the recycling of resources, save a lot of energy, and promote the sustainable development of economy and society!
