The scrap board crushing and recycling production line is mainly used for the separation of metal and non-metal in materials such as waste circuit boards, copper clad laminates, circuit boards, and leftover materials.

1. Good overall performance, with unique effects on computer board recycling, computer board recycling, TV board recycling and other circuit control board recycling. It also has compatibility for the recycling of various circuit boards containing capacitors.

2. This production line is an upgraded product of Type A products. On the basis of Type A, it consumes less power, has no noise, less labor, high automation procedures, improved efficiency, and a small area. It is ideal for recycling waste circuit boards. Production line.

3. The whole set of equipment adopts a new type of dust collector, three-in-one dust removal (cyclone dust removal + electrostatic dust removal + static dust removal) to the air, without exhaust gas emission.

4. The appearance of the equipment is clean and tidy, and there is no dust bag, which replaces the problems that cannot be solved by traditional dust collectors.

5. In order to prevent dust pollution during processing, a pulse dust removal device is added after the air flow sorting process, which effectively solves the problem of dust pollution.

Process flow:

1. Shredder: Shred the light board to 2-3 cm.

2. Circuit board crusher: crush the crushed circuit board to about 20 mesh.

3. Analyzer: the crushed material is air sorted, resin, copper, dust, and fiber are separated. The dust and fiber are sucked into the collector by the induced draft fan, and the resin and copper enter the grading sieve.

4. Collector: Collect dust and fibers, and discharge the collected fibers.

5. Pulse purifier: collect the dust and superfine fibers generated in the crushing process.

6. Classification screen: screen the resin and copper. The resin and copper that are not separated are returned to the main machine and then pulverized. The separated resin and copper enter the specific gravity separator for separation.

7. Specific gravity sorting: resin powder and copper are sorted by specific gravity. Since 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. In this way, the separation of metal and non-metal is achieved. This is currently the most advanced technology in China, which can achieve a metal separation effect of more than 99%.

8. High-voltage electrostatic sorting: The tail material that has passed through the specific gravity sorting machine is subjected to high-voltage electrostatic sorting to separate the small copper powder contained in the tail material from the resin (the principle of high-voltage electrostatic sorting is: the input power is passed through the transformer Adjust to a high voltage of 100,000 volts to form a high-voltage magnetic field, which has an adsorption effect on conductive metals, so that the separation of metals and non-metals is achieved)
