What is the process of recycling copper from PCB boards by machine?

PCB boards were regarded as waste by most people. Actually, PCB boards can be recycled to get copper and other kinds of metals, which can be sold at a good price. Whether you want to know what machine can be used for recycling copper from PCB boards or what the process of recycling copper from PCB boards is? In this article, I will talk about them in details.

PCB crushing and separating machine is a complete production line, which is specially designed for recycling copper from PCB boards. The production line of PCB crushing and separating machine is equipped with shredder, crusher, eddy- vibrating screen, air separator and electrostatic separator. The detailed working process of recycling copper from PCB boards is as following introduction.

The process of recycling copper from PCB boards

First, put waste PCB boards in the shredder. The PCB boards can be shredded into small pieces from 2 to 5 cm.

Second, the shredded PCB board pieces are transported on a conveyor belt to the crusher. There will be a magnetic separator on the conveyor belt to sort iron out.

After crushing, PCB boards pieces are basically around 4 mm.

Then the eddy-vibrating screen can control the size of PCB boards. If there are some particles bigger than 4mm, they will return into eddy vibrating screen for second crushing. Small particles can be transported into air separator through the wind system.

Air separator will separate copper from non-metal

And air separator will separate copper from non-metal according to the different specific gravity of them. If you have higher requirement for separation rate of the machine, the PCB crushing and separating machine can be equipped with electrostatic separator. With the use of electrostatic separator, the separation rate can reach to 99%.

It should be noted that when processing different kinds of waste circuit boards, the separated metals will be a little different. When processing cell phone boards and computer motherboards, the metals will contain gold, Plumbum, tin and some other precious metals. When processing circuit boards taken apart from household appliance, the metals are mainly copper.
