The circuit board contains a large number of precious metals and rare materials, such as gold, silver, copper, indium, etc., which have a high value. With the right technology and processes, these precious materials can be extracted and used to produce new electronic products. This can not only save resources and reduce the damage to the natural environment, but also effectively reduce production costs. Therefore, discarded PCBs should not simply be seen as garbage, but as a valuable resource.
Waste circuit board crushing and sorting equipment is a set of treatment methods for dismantling and decomposing scrap circuit boards into metal and non-metal. A circuit board with electronic components, which has been disassembled and the components removed. The circuit board completes the dissociation of metals and non-metals through coarse crushing, iron removal, and fine crushing to form a mixture of metals and non-metals, which enters the airflow gravity screen to extract most of the metal objects. The circuit board fiber powder screened out by the airflow contains a small amount of fine metals, and then enters the electrostatic separator to extract the remaining fine metals to achieve a larger metal rate.
The harmless treatment of waste PCB circuit boards can not only reduce its harm to the environment, but also enable a large number of valuable resources to be reused, which is of great significance for improving the living environment of human beings, the reuse of resources and sustainable development.
