How to remove metals from circuit boards without chemicals?

Circuit boards are widely used in our daily life, such as computer, TV, air conditioner and so on. There are different amount of metals in the circuit boards. If we can recycle them without chemicals, we can get high profit because of the high purity of metals. Well, how to remove metals from circuit boards without chemical? This article will give you the answer.

In order to remove metal from circuit boards without chemical, Henan Doing Environmental Protection Technology Co., Ltd designed a PCB board crushing and separating machine. It is specially designed for processing various circuit boards. The mainly process of the machine is shredding, crushing, sieving and separation. Firstly, these PCB boards will become small particles through the shredder and crusher. Then these small particles will go through the magnetic separator, which will remove the iron. After removing iron, these small particles will flow into the eddy-vibrating screen. The eddy-vibrating screen is mainly to control the size of metal and resin & fiber remain about 20-24 mesh. The bigger particles will be sent back to the crusher to further crushing. Then the air separator will do the first separation according to the different weight. Some particles of metals and non-metals have the similar weight, which can not be separated by air separator. So we need an electrostatic separator to help us get a higher separation rate. Because the metal and plastic have different electrical conductivity.

The whole working process is a physical way, there is no chemicals used, no water and no fire. It is a total environmental friendly machine. This machine will not damage the metals, so we can get high purity of metals with 99%. If you are interested in PCB board crushing and separating machine, you can contact us.
