What are the difficulties in recycling waste circuit boards? How to deal with it?

250-300 grams of gold, 0.7-1.5 kilograms of silver, and 120-150 kilograms of copper can be separated from one ton of waste circuit boards. Recycling waste circuit boards have high recycling value and economic benefits. But, there are many difficulties in recycling waste circuit boards. Doing has developed an E waste PCB recycling machine to address these difficulties. What difficulties does it solve? Let's find out!

1.The difficulty of poor separation effect

The first difficulty in recycling waste circuit boards is separation effect. There are many ways to recycle waste circuit boards, such as fire burning, chemical dissolution, etc. These methods can realize the separation of metal and resin powder in waste circuit boards. However, although they can separate metal and resin powder, metal and non-metal will stick together during processing, the separation rate of metal and non-metal will be greatly reduced, and the overall recovery rate of waste circuit boards will also be reduced. Doing engineers design a E waste PCB recycling machine according to the characteristics of waste circuit board to deal with the difficulties in recycling waste circuit boards.

E waste PCB recycling machine

Doing E waste PCB recycling machine adopts a dry physical separation method. It does not use fire or chemicals in the whole process, and will not damage the waste circuit boards. Different from other machines on the market, our E waste PCB recycling machine adopts double crushing. The degree of crushing of waste circuit boards not only affects the energy consumption of the crushing equipment, but also affects the subsequent sorting efficiency, so crushing is a key step. In addition to air separation, it is equipped with electrostatic separator which can separate metal and resin powder in a closed magnetic field by using the different conductivity between them, and the separation rate can reach 99%.

2.The difficulty of low quality of metals and non-metals

Although fire combustion and chemical dissolution can separate metal and resin powder, fire and corrosive chemicals will also destroy the quality of metal while separating non-metal, and the price of metal will drop, which will eventually lead to the loss of economic benefits. In order to deal with this difficulty in recycling waste circuit boards, a breakthrough has been made in configuration of Doing E waste PCB recycling machine.

Usuage of metals and resin & fiber

Doing E waste PCB recycling machine uses air and electrostatic separator to separate metal and non-metal through the process of crushing and sorting. Although turned into powder, the quality of metal and non-metal will not be damaged at all. So the separated metal can be sold directly to metal trading market or purification plant, and the separated resin powder can also be sold directly as raw materials for plastic wood, outdoor benches, and floors, or as fillers for wood-plastic products. The common benefits of metal and resin powder greatly improved economic benefits.

3. The difficulty of environment protection

The last difficulty in recycling waste circuit boards is dust. Due to the dust carried by the waste circuit board itself, it will inevitably cause pollution to the working environment during the processing process. And if people are in the dusty environment for a long time, it is easy to cause various respiratory inflammations and endanger human health.

Pulse dust system

Doing E waste PCB recycling machine adopts a fully enclosed pipeline transportation method, the dust will not leak out. And is equipped with a pulse dust removal system to collect dust during processing, which not only protects the health of workers, but also protects the environment. It is worth mentioning that the bag of the pulse dust removal system is customized with specific materials, using needle-punched felt cotton, which not only has a good adsorption effect, but is also more durable than ordinary cotton bags.

Advantages of E waste PCB recycling machine

Doing is among those companies who are prominent in recycling e-waste including waste circuit boards recycling in their services. They follow all the necessary steps to properly recycle waste circuit boards professionally and securely. If you choose Doing E waste PCB recycling machine, the above-mentioned difficulties in recycling waste circuit boards can be ignored.
