       The specific application of mechanical treatment technology of circuit board recycling equipment, electronic waste disposal of waste printed circuit boards, has been a rather complex problem. According to the combination of various components in the waste circuit board, circuit board recycling equipment using mechanical methods of material separation, is an economical and environmentally compatible means of treatment. The disposal of waste printed circuit boards from electronic waste has always been a complex issue. According to the combination of various components in the waste circuit board, the mechanical method of material separation is an economical and environmentally compatible means of treatment. This paper introduces the various mechanical equipment used in the technology of reuse of waste circuit boards and summarizes the progress of foreign mechanical disposal methods.

       With the widespread use of electronic and electrical products in recent years, the amount of electronic waste is increasing day by day, coupled with the rapid replacement of electronic and electrical products, every short time will produce a full range of electronic and electrical products, people will discard a large number of electronic waste. GreenJet environmental protection circuit board recycling equipment can be all kinds of waste circuit boards, computer boards, TV boards, aluminum-plastic boards, attached copper boards, printed circuit boards and processing waste, waste electrical appliances and other mechanical crushing recycling treatment. Circuit board recycling equipment mechanical processing technology commonly used in what equipment?

       1. belt conveyor, 2. primary shredder 3. secondary crusher, tertiary crusher 4. Z gravity analysis machine 5. elevator 6. gravity sorting machine 7. vibrating screen 8. feed high pressure fan 9. pulse dust collector 1. plc control system 11. magnetic separator 12. high voltage electric separation machine 13. electrostatic separator platform 14. screw conveyor

       Circuit board recycling equipment mechanical processing process: from the conveyor to send the circuit board into the shredding crushing machine to shred the circuit board, and then directly into the crusher crushed particles, and then sent by the feed screw into the three-stage crusher for crushing, the crusher belongs to the integrated water-cooled crushing, in the case of ensuring the normal temperature of the machine, the mesh to 30-80 mesh, the crusher comes with a grading sifter, in the crushing process 30-80 mesh circuit board powder into the next link, not up to the requirements of the cycle again. 30-80 mesh circuit board powder into the next link wind specific gravity separator, according to the specific gravity of copper powder and resin fiber powder for primary separation, can be separated out of about 98% of the metal powder, specific gravity separator separated from the powder and the upper extraction of the powder into the pulse dust collector, the pulse dust collector unloaded powder Inside contains a small amount of copper powder, and then sent by the wind feeder into the high-voltage electrostatic separation equipment for the next step of separation.
