What is an e-waste recycling plant?

E-waste recycling plant is the plant to recycle and reuse the electronic waste to get the recyclable precious metals, which mainly includes waste circuit board recycling machine, waste cable wire recycling machine and waste radiator recycling machine.

1. Waste circuit board recycling machine

Waste circuit board recycling machine

Waste circuit board recycling machine is the main e-waste recycling plant, which is mainly used for the separation of metal from non-metal in all kinds of waste circuit boards and other materials. Besides, it can destroy the data on the circuit boards.

Raw materials:

Waste circuit boards

Waste circuit board recycling machine can process all kinds of waste circuit boards, like computer mother boards, printed circuit boards, mobile phone boards, TV boards, refrigerator boards, copper clad laminate, etc.

Working process:

1). Send the waste circuit boards into shredder through a belt conveyor; the double-shaft shredder will shred the complete waste circuit boards into small pieces;

2). Use hammerhead crusher and hammer crush to pulverize the small pieces into a mixture with a particle size of about 2.5 mm; between the two crushing, a magnetic separator will be used to remove the iron.

3). Eddy-vibrating screen will be used to control the size - the bigger particles will be sent back to hammer crusher for further crushing; and the small enough particles will pass through the eddy-vibrating screen;

Working process

4). Separate the metals and non-metals according to their different gravity and conductivity by using air separator and electrostatic separator;

5). Collect the dust by pulse dust collector and cyclone dust collector.

The following is a 3D working video of waste circuit board recycling machine, which can help you get a good understanding of the working process.

Final products and application:

Metals:

1). The separated metals has high purity and good quality, which can be sold directly to the metal trading market;

2). The metals are usually copper, gold, silver, tin, palladium, chrome and other rare elements, which can be purified and sold；

3). Since 90% of the mixed metal is copper, it can also be sold to copper smelters.

Final products and application

Non-metals:

1). The non-metals are resin fiber, which can be sold directly, but with low price;

2). Further processing and re-sale: grind to 80 mesh to make filler of resin tile and building brick; grind to 120 mesh to make ground paint; grind to 300 mesh to make heat insulation material and fireproof material.

2. Waste cable wire recycling machine

Waste cable wire recycling machine

Waste cable wire recycling machine is another e-waste recycling plant, which is used to recycle the used scrap copper wire cables, so as to obtain the copper and plastic inside. Because the copper granule looks like rice, waste cable wire recycling machine is also called cable wire granulator.

Raw materials:

Waste cable wires

Waste cable wire recycling machine has wide application in many fields, such as scrap automotive or old vessel circuitry, telecommunication cable wire, kinds of civil wires, computer or laptops circuitry or wire, abandoned or junk wires or cable, etc.

Working process:

The parameter and configuration of waste cable wire recycling machine is different, the workflow may be a little different. The whole working process is as follows:

1). Shredding - Using a double-shaft shredder to shred waste cable wires into small pieces about 5-8cm;

2). Crushing - Using a knife crusher to crush these small pieces into small particles;

Working process

3). Separation - Using an air separator and electrostatic separator to separate copper from plastic according to their different gravity and conductivity with 99% separating rate

4). Dust removal - Using pulse dust and cyclone dust removal system to collect the dust with the collect rate of 99.5%.

The above is a waste cable wire recycling machine's 3D working video, which shows the whole working process.

Final products and application:

1). Copper: The separated copper usually has high purity and good quality, which can be directly sold to the metal trading market, and the selling price is pretty considerable. In the case of large quantities of copper, it is possible to directly sell it to copper electrolytic plants or copper factories.

Final products and application

2). Plastic: The plastic pellets can be used to manufacture various new plastic products such as rubber mattresses, insoles, and even wire covers. Of course, it also can be sold to plastic collectors directly.

3. Waste radiator recycling machine

Waste radiator recycling machine

The waste radiator recycling machine is the other e-waste recycling plant. As the name suggests, waste radiator recycling machine is the machine for processing the waste radiators to separate aluminum, copper and iron out. It is also called copper aluminum radiator recycling machine.

Raw materials:

Waste radiators

Waste radiator recycling machine is used to recycle all kinds of waste radiators, including air conditioner radiators, car water tanks, condensers, refrigerator crushed materials, etc.

Working process:

The 3D working video of waste radiator recycling machine is as follow:

1). Put waste radiators into shredder to shred them into small pieces.

2). Use hammer crusher to crush these small pieces into small particle in 2-3cm.

3). Use negative-pressure baffling separator to separate most aluminum first.

4). Use air separator to separate copper and rest aluminum.

5). During process, collect dust by pulse dust collector.

Final products and application:

Final products and application

The separated copper and aluminum are usually sold to metal trading market directly, or made into copper or aluminum ingots to sell.
