What are the methods for recycling circuit boards? What are their characteristics?

Waste printed circuit boards can be recycled to get mixed metals, like gold, sliver, copper, and other precious metals and rare metals, for profit. But do you know how to recycle waste printed circuit boards? There are many different methods, such as burning, manual dismantling and dry type crushing and separating. In this article, I will make a detail introduction about these methods.

Burning is the traditional way to recycle waste printed circuit boards. Just through burning the waste printed circuit boards, you will get metals. This is a fast way to get metals. However, burning will produce waste gas pollution, which is not only harmful to human health, but also pollute the environment. Besides, the quality of mixed metals will be affected by burning. Therefore, the price of metals will be decrease. This method has not been welcomed by recyclers in recent years.

Fire treatment to recycle circuit boards

The second method is manual dismantling. This method will need a lot of labor force. And its working efficiency is pretty low, which maybe only dismantling dozens of kilograms of circuit boards per day. In addition, if dismantling circuit boards by manual for a long time, it will cause severe respiratory infections and harm to human health. So it is not a proper way to recycle printed circuit boards.

The third method is dry type crushing and separating method - PCB recycling machine. PCB recycling machine is also called PCB crushing and separating machine, which is specially designed for recycling waste printed circuit boards to get mixed metals for profit. It is a new type technology, adopting dry type physical separation method to recycle waste printed circuit boards. Through crushing, sieving and electrostatic separator, you will get mixed metals and resin fiber. They can be sold directly on the market. The whole process without using chemicals, water or fire, thus no pollution to the environment.And the pulse dust removal system will collect the dust, which will not pollute the air. It maybe the best choice for recyclers to start PCB recycling business.
