E-waste Recycling Production Line

1.Introduction to Electric (Line) Road Board Crushing and Recycling Equipment:
Main points of electronic waste crushing and recycling equipment products: The waste circuit board crushing and recycling production line is mainly used to separate metal and non-metal materials such as waste circuit boards, copper clad boards, circuit boards, and scraps. The successful development of this machine not only improves the quality of recovered copper, but also prevents secondary pollution. This production line adopts secondary crushing to regenerate and process waste circuit boards, making them a mixture of metal and resin fiber powder; Then, the metal and resin are separated by wind and electrostatic separation. To prevent dust pollution during the processing, a pulse dust removal device was added after the airflow sorting process, effectively solving the problem of dust pollution.
 

2.Introduction to Electrical (Wire) Board Equipment Products
The waste board crushing and recycling production line is mainly used to separate metals and non-metals from materials such as waste circuit boards, copper clad boards, circuit boards, and scraps.
1. Good overall performance, with unique effects on computer board recycling, computer board recycling, TV board recycling, and other circuit control board recycling. The recycling of various circuit boards containing capacitive devices also has compatibility. 
2. This production line is an upgraded version of the A-type product. Based on the A-type, it has reduced power consumption, no noise, fewer manual labor, high automation programs, improved efficiency, and a small footprint. It is an ideal production line for recycling and reusing waste circuit boards to the present day
3. The entire set of equipment adopts a new type of dust collector, with a three in one dust removal (cyclone dust removal+electrostatic dust removal+static dust removal) for air and no exhaust emissions.
4. The equipment has a neat appearance and no dust removal bags, replacing the problems that traditional dust collectors cannot solve with dust and odors.
5. To prevent dust pollution during the processing, a pulse dust removal device was added after the airflow sorting process, effectively solving the problem of dust pollution.
 

3.Characteristics of electrical (wire) circuit board equipment:
1. A new process of mechanical crushing and high-voltage electrostatic separation using a circuit board crusher has been adopted.After disassembly, crushing, and dissociation, metal and non-metallic materials are sorted with high purity. The separation purity of the entire circuit board equipment should reach over 99.5%.
2. The key technology is to organically combine specialized crushing and dissociation equipment for various waste circuit boards, achieving significant energy-saving effects in the production process and achieving high metal separation rates.
3. The unit energy consumption per ton of waste circuit board processed by circuit board equipment is only about 3/5 of that of similar domestic products; A single set of equipment has a capacity of 1 ton per hour.
4. The price of circuit board equipment is only 1/5-1/3 of that of similar equipment both domestically and internationally, and the copper recovery rate is 3% -5% higher than that of similar manufacturers.
5. Good overall performance, with unique effects on computer boards, computer boards, television boards, and other circuit control boards. The recycling of various circuit boards containing capacitive devices also has compatibility.
6. The circuit board equipment production line is an upgraded product of wind selected products, which reduces power consumption compared to wind selected products, and has no noise, fewer manual labor, high automation program, improved efficiency, and a small footprint. It is an ideal production line for recycling waste circuit boards at present.
7. With minimal labor and no noise, the placement of circuit board equipment is flexible.
 

4.Process flow diagram:
1. Shredder: shred the light board to 2-3 centimeters.
2. Circuit board crusher: Crush the crushed circuit board to about 20 mesh.
3. Analysis machine: The crushed material is selected by air, separating resin, copper, dust, and fibers. The dust and fibers are sucked into the collector by the induced draft fan, and the resin and copper enter the grading screen.
4. Aggregator: Collect dust and fibers, and discharge the collected fibers.
5 Pulse purifier: collects the dust and ultrafine fibers generated during the crushing process.
6. Grading screen: The resin and copper are screened, and the resin and copper that have not been separated are returned to the main machine for crushing. The separated resin and copper enter the specific gravity sorting machine for sorting.
7. Specific gravity sorting: Sort resin powder and copper by specific gravity. As the weight of copper is greater than the weight of resin, copper will be sorted to one side and resin will be sorted to the other side. This achieves the separation of metals and non-metals. 
8. High voltage electrostatic sorting: The tailings that have passed through the gravity sorting machine are then subjected to high voltage electrostatic sorting to separate the small copper powder and resin contained in the tailings. The principle is to adjust the input power supply to a high voltage of 100000 volts through a transformer, forming a high-voltage magnetic field that has an adsorption effect on conductive metals, thus achieving the separation of metals and non-metals.
