       The current market of used circuit boards are mainly household appliances, computers and other circuit boards, so they can be divided into several categories for recycling, with electronic components need to be manually disassembled first, then disassembled and recycled with circuit board recycling equipment; without electronic components can be directly crushed and recycled. At present, the recycling of used circuit boards has become an industry, the development of society has far-reaching significance. Recovery of used circuit boards, you can reduce the waste of resources, environmental pollution and other issues. The equipment and process of recycling waste printed circuit boards by physical methods, mainly including the crushing and dissociation of waste printed circuit boards, the separation of metals and non-metals by dry and wet sorting technology.

       Waste circuit board recycling equipment includes shredder - crusher - screening device - air-flow specific gravity sorter - electrostatic sorter - pulse dust removal and many other individual machines; each individual machine operates in coordination with each other to achieve a stable, environmentally friendly operating production model. The role and process flow of each single machine used in the waste circuit board recycling equipment are described below in order
       1, the role of the shredder in the waste circuit board recycling equipment is to first shred the whole circuit board into a 5-7cm block, and then transported to the crusher by conveyor belt.

       2, the crusher uses the hammer secondary crushing, the use of impact will be block waste circuit board crushing, so that it becomes a mixture of metal and resin fiber powder, after the waste circuit board recycling equipment in the lifting device sent to the screening process for processing;.

       3, sieving device using rotary vibration sieving to achieve a fully enclosed structure, the use of vibration sorting technology, the crushed particles up to standard metal and resin powder by the sieve screen, and then sorted; substandard particles continue to cycle crushing.

       4, waste circuit board recycling equipment sorting process using two sorting. The first sorting by the air proportional sorting machine sorting, secondary sorting by electrostatic sorting machine sorting; two sorting process using metal, resin powder powder different gravity and charged sorting, can achieve complete separation of metal and resin powder in the waste circuit board, sorting, sorting purity can reach more than 99%.

       Waste circuit board recycling processing equipment is mainly used to recycle and process waste circuit boards, memory sticks, graphics cards and other electronic products equipment, the metal and resin powder in the waste circuit board can be sorted out, sorted out the metal and resin powder can be used as raw materials processing.
