Circuit board scrap recycling machine

Circuit board scrap recycling machine is a kind of e waste recycling machinery, which is specially designed for processing waste circuit boards, to separate precious metals for recycling use. Besides, it can also destroy the data on the boards, to protect our privacy.

Raw materials of circuit board scrap recycling machine:

Circuit board scrap recycling machine can process many different types waste circuit boards, such as printed circuit board, computer mother boards, mobile boards, copper clad laminate, circuit board scraps, etc.

Waste circuit boards

Parameter of circuit board scrap recycling machine:

Due to the different amount of waste circuit boards collected, there are also different processing capacities of circuit board scrap recycling machine.

Working process of circuit board scrap recycling machine:

Because there are different parameter and configuration of circuit board scrap recycling machine, the workflow may be a little different. The whole working process is as follows:

Shredding:

Use double-shaft shredder to shred the waste circuit boards into small pieces;

Crushing:

Then hammerhead crusher and hammer crusher will be used to crush these pieces into small particles. Between the two crusher, a magnetic separator will separate the iron from the crushed materials ;

Working process

Sieving:

Eddy-vibrating screen is used to control the size of particles. Bigger particles will be stopped by eddy-vibrating screen and be sent back to the second crusher for further crushing; the small particles will go through the screen to the next step.

Air separation:

Air separator takes advantage of the different density of metal and non-metals, to separate precious metals and resin fiber out.

Electrostatic separation:

Due to the completely crushing, the density of some metals is similar with non-metals. So the air separator can't separate them clearly. Then electrostatic separator will be used to separate the fine metals from resin fiber according to the conductivity.

The above is the working video of circuit board scrap recycling machine, which can help you get a better understanding.

PCB dismantling machine

Tips: If there are electronic components on the waste circuit boards, you can use a PCB dismantling machine to dismantle the electronic components from waste circuit boards firstly. The electronic components dismantled from waste circuit boards could be sold separately.

Final products of circuit board scrap recycling machine and its usage:

Final products and application

1. Precious metals: The separated metals of circuit board scrap recycling machine usually has a good quality. They can be sold directly in the metal trading market, or to extract the precious metals and sell them after further processing.

2. Resin fiber: They are usually made to the filling material for making resin tiles, ground painting, wood-plastic products, etc. But if they are ground to about 300 mesh, they can be used as heat and fire insulation materials.

Advantages of circuit board scrap recycling machine:

1. Good material

Double-shaft shredder

The material of circuit board scrap recycling machine adopts excellent materials, which make it has longer use life. For example, the double-shaft shredder is made of H13 alloy, and the crusher is made of 65Mn, which has high hardness and weariness.

2. High separating rate

Electrostatic separator

Circuit board scrap recycling machine uses two separation processes of air separation and electrostatic separation, which can separate fine metals from resin fiber according to their different gravity and conductivity with the separating rate of 99%.

3. Environmental friendly

Circuit board scrap recycling machine has changed traditional method of burning and corroding the waste circuit boards, recovering precious metals by physical crushing, separation and dust collect, which has any pollution to environment.
