The Waste Circuit Board Crushing and Recycling Production Line is primarily used for separating metals and non-metals from waste circuit boards, copper clad boards, PCBs, and scraps. The successful development of this machine not only enhances the quality of recycled copper but also prevents secondary pollution. The production line employs a two-stage crushing process for waste circuit boards to create a mixture of metal and resin fiber powder. Subsequently, the metal and resin are separated through wind and static sorting. To prevent dust pollution during the processing, a pulse dust removal device is added after the air flow sorting process, effectively resolving the dust pollution issue.

The waste circuit board crushing and recycling production line is mainly used for the separation of metals and non-metals from waste circuit boards, copper clad boards, PCBs, and scraps.

1. Excellent overall performance, effective for the recycling of computer boards, computer panels, TV boards, and other circuit control boards. Also compatible with the recycling of various circuit boards containing capacitor components.

2. This production line is an upgraded and replaced model for the A-type product. It consumes less electricity, produces no noise, requires fewer workers, and has a high level of automation, improving efficiency. Additionally, it occupies less space, making it an ideal production line for recycling and utilizing old circuit boards to date.
3. The complete set of equipment features a modern dust collector, incorporating a three-in-one dust removal system (cyclone dust removal + electrostatic dust removal + static dust removal) for air purification, with no waste gas emissions.
4. The equipment boasts a clean appearance, free of dust bags, overcoming the traditional dust collectors' inability to address dust and odors.

5. To prevent dust pollution during the processing stage, a pulse jet dust removal unit is added after the air flow sorting process, effectively solving the dust pollution issue.

Printed Circuit Board Shredder Recycling Process Flowchart

Shredder: Shreds the bare board into pieces measuring 2-3 centimeters.

2. PCB Shredder: Shreds the shredded circuit boards to around 20 mesh.

3. Analysis Machine: The crushed material is air-sorted to separate resins, copper, dust, and fibers. The dust and fibers are drawn into the collector by an exhaust fan, while the resins and copper are fed into a grading sieve.

4. Collector: Collects dust and fibers; the collected fibers are then emitted.

5. Pulse Purifier: Collects dust and ultra-fine fibers generated during the crushing process.

6. Grading Screen: Separates resins from copper. Resins and copper that are not separated are returned to the main machine for further crushing, while the separated resins and copper are then processed in a density separator for sorting.

7. Density Separation: Perform density separation on the resin powder and copper. Since the weight of copper is greater than that of the resin, the copper will be separated to one side, while the resin will be separated to the other. This achieves the separation of metal from non-metal. It is a technology currently available in China that can achieve metal separation effectiveness of over 99%.

8. High-voltage Electrostatic Separation: Further separate the tailings from the gravity separation machine through high-voltage electrostatic separation, enabling the separation of fine copper powder and resin contained in the tailings (The principle of high-voltage electrostatic separation is: adjust the input power through a transformer to 100,000 volts of high voltage, forming a high-voltage magnetic field, which has an adsorption effect on conductive metals, thereby achieving the separation of metals from non-metals).

PCB Shredder Recycling Equipment Performance Parameters

Economic Analysis of Electric (Wiring) Board Recycling Equipment
Total production line power: 98 Kw, processing capacity: 700 Kg/h, copper content in circuit boards is approximately 18% (copper content varies in different types of recycled circuit boards, generally between 13%-35%), 5 operators.
(1) Estimated Output Value (calculated based on 300 days a year, 8 hours per day)
(a) Annual copper production approximately: 300(days) × 8(hours) × 700(Kg) × 18%(copper content) = 302.4 tons copper. At a price of 50,000 yuan/ton, the annual copper value is: 302.4 × 5 = 1,512 (10,000 yuan)
(b) Annual output of glass fiber powder approximates to: 300(days) × 8(hours) × 700(kg) × 82%(content) = 1377.6 tons. At a price of 1000 yuan/ton for glass fiber, the annual value of non-metallic materials is: 1377.6 × 0.1(thousand yuan) = 137.76 thousand yuan.
(c) Total annual output: 1512 + 137.76 = 1649.76 (10,000 yuan)
(2) Estimated
(a) Annual electricity consumption (with electricity cost at 0.8 yuan/kWh): 100 (Kw) × 300 (days) × 8 (hours) × 0.8 (yuan/kWh) = 19.2 (10,000 yuan)
(b) Labor cost: 2000 RMB per person/month × 12 months × 5 people = 120,000 RMB
(c) Depreciation Expense (at 10% depreciation), approximately: 260,000 × 10% = 26,000 (10,000 RMB)
(d) Repair Costs Approx.: 10,000 RMB
(e) Scrap Circuit Board Purchase Fee: 300 (days) × 8 (hours) × 700 (Kg/h) × 6 (RMB/Kg) = 1,008 (Ten thousand yuan)
Rent: 2000 RMB/month × 12 months = 24,000 RMB
Total: 19.2 + 12 + 2.6 + 1 + 1008 + 2.4 = 1034.2 (10,000 RMB)
Gross Profit: 1649.76 - 1034.20 = 615.56 (Ten Thousand Yuan)
