The application and production of circuit board recycling equipment, from reducing and gradually limiting the pollution and reuse of circuit boards, circuit boards, laminates, at the same time, but also to promote the development of environmental protection industry, encourage, guide the recyclable green products, our company launched environmentally friendly circuit board recycling equipment equipment, circuit board recycling equipment gradually end-of-life circuit board recycling of metal materials.
Circuit board recycling equipment is the end-of-life circuit board disassembly decomposition and separation into a set of metal and non-metal processes, with electronic components of the circuit board, and then after the detinning, disassembly, remove the components, not through the disassembly of electronic components can also be directly crushed and separated. Circuit boards through coarse crushing, iron removal, fine crushing to complete the dissociation of metal and non-metal, the formation of a mixture of metal and non-metal, into the airflow specific gravity sieve, most of the metal extracted. The circuit board fiber powder from the airflow specific gravity sieve contains a small amount of fine metal, and then enters the electrostatic sorter to extract the remaining fine metal to achieve a large metal recovery rate.
The recycling process of circuit board recycling equipment mainly includes two-stage crushing, electrostatic sorting, metal recovery and reuse of non-metallic materials. First of all, a combination of rotary crusher and impact rotary mill is used for primary crushing and secondary crushing to achieve the degree of full dissociation of metal-nonmetal, and then a roll-type corona-static compound electric field high-voltage electric separator is applied to the crushed waste circuit boards for sorting of metal particles and nonmetal particles.
Xingmao environmental protection circuit board recycling equipment advanced, mature recycling of waste circuit board comprehensive utilization of production technology, the raw material crushing, fine crushing, feeding, sorting process processing, the process technology used in the same industry at home and abroad in the leading level, the technical route is feasible.
