How to properly recycle the waste PCB

The circuit board is also called PCB. It is composed of base material, base copper, electroplating layer and surface protection paint. The base material is composed of synthetic resin and glass fiber. Plated with nickel or gold or silver or tin, a circuit board contains precious metals copper, gold, silver, palladium, platinum and so on. These discarded circuit boards can usually recover 80%-90% of precious metals, and the resource utilization of circuit boards can be realized through some processing methods. The discarded circuit board is the core of the entire electronic waste, and it is also a difficult part to deal with.

A set of circuit board recycling equipment is energy-saving and environmentally friendly to achieve innovation and sustainable development. The waste circuit board recycling equipment has compact structure, reasonable layout, stable performance and low noise. The equipment adopts PLC to control the whole production line to feed materials evenly and coordinate the operation.

This process does not need to disassemble circuit boards containing electrical components, circuit boards and other raw materials, and can directly enter the production line for processing and production. The materials are separated and recovered through primary coarse crushing, magnetic separation, secondary fine crushing, dust collection, winnowing, vibration screening, specific gravity separator, electric separation and other processes, and the recovery rate can reach more than 99%. The process is fully automated from feeding to sorting, and only needs 1-2 people to operate. The process is physical dry separation, without heating, incineration, water and chemical raw materials, low cost, high efficiency, and normal temperature dry separation without any pollution.
