Circuit board recycling equipment

Brief introduction

The scrap circuit board crushing and recycling supply line is mainly used to separate metal and non-metal materials from waste circuit boards, copper-clad boards, circuit boards, and scraps. The successful development of this machine not only improves the quality of copper recovery, but also prevents secondary pollution. This supply line adopts secondary crushing to customize the regeneration of 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 customization process, a pulse dust removal device was added after the airflow sorting process, effectively solving the problem of dust pollution.

Characteristics

The scrap board crushing and recycling supply line is mainly used to separate metal and non-metal materials from waste circuit boards, copper-clad boards, circuit boards, and scraps.

1. Good overall performance, effective in computer board recycling, computer board recycling, TV board recycling, and other circuit control board recycling. The recycling of various circuit boards containing capacitive devices is also compatible.

2. This supply line is an upgraded version of A-type products. Based on A-type, it reduces power consumption, has no noise, requires less labor, has high automation programs, and improves efficiency. At the same time, it occupies a small area, making it an ideal supply line for recycling and reusing waste circuit boards.

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+electrostatic dust removal), and no exhaust gas emissions.

4. The appearance of the equipment is clean, replacing the problems that traditional dust collectors cannot solve with dust and odors.

5. To prevent dust pollution during the customization process, a pulse dust removal device was added after the airflow sorting process, effectively solving the problem of dust pollution.

Advantage

1. A new process of mechanical crushing and high-voltage electrostatic separation was adopted using a circuit board crusher. After disassembly, crushing, and dissociation, metal and non-metal materials are sorted with high purity. The separation purity of the complete circuit board recycling equipment should reach over 99.5%.

2. The key technology is to organically combine various specialized crushing and dissociation equipment for waste circuit boards, achieving good energy-saving effects in the supply process and achieving high metal separation rates.

3. The unit energy consumption per ton of discarded circuit boards processed by circuit board recycling 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 at high altitude.

4. The price of circuit board recycling equipment is only 1/5-1/3 of that of similar equipment, and the copper recycling rate is 3% -5% higher than that of similar supply companies.

5. Good overall performance, effective for computer boards, computer boards, TV boards, and other circuit control boards.

Process flow

1. Shredder: Tear the light board into small pieces to 2-3 centimeters.

2. Circuit board crusher: Crush the crushed circuit board to around 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. Graded screening: The resin and copper are screened, and the resin and copper that have not been separated are returned to the main machine for further crushing. The separated resin and copper are then fed into a 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. The metal sorting effect reaches over 99%.

8. High voltage electrostatic sorting: The tailings that have passed through a specific 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 of high-voltage electrostatic sorting 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)
