The number of discarded printed circuit boards, the main component of electronic waste, is also increasing, and the pollution caused by used PCBs to the environment has caused concern in various countries. In the waste PCB, containing heavy metals such as lead, mercury, hexavalent chromium, as well as polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) and other toxic chemicals as components of flame retardants, these substances in the natural environment, will cause huge pollution of groundwater, soil, and bring harm to people's lives and physical and mental health. In the scrap PCB, containing nearly 20 kinds of non-ferrous metals and rare metals, has a high recycling value and economic value, if you can reasonably effective treatment of used circuit boards, extract the metal, it really realized the electronic waste into a metal recycling "money tree".
Xingmao machinery according to the market demand and a large number of electronic waste can not deal with the trouble, invested a lot of time and effort to the market launched the circuit board processing equipment, circuit board processing equipment is also called circuit board recycling equipment. The equipment can guarantee environmental protection under the premise of a large number of waste electronic waste recycling treatment, processing capacity, good metal sorting effect is the advantage of the equipment. With the continuous penetration of intelligent technology, automatic control is also used in the rapid development of the equipment, so that people's operation is more convenient and fast.
In order to let users more profound understanding of the process of waste circuit board processing equipment, Shibang machinery around the physical method, crushing and sorting for a brief description: 1, physical method: the physical method is the physical method is the physical method, crushing and sorting.
1, physical method: physical method is the use of mechanical means and PCB physical properties of the different methods to achieve recovery.
2, crushing: the purpose of crushing is to make the metal in the waste circuit board as much as possible and organic matter dissociation, in order to improve the sorting efficiency. When crushed in 0.6 mm, the metal can basically reach 100% dissociation, but the choice of crushing and the number of stages depends on the subsequent process.
3, sorting: sorting is the use of material density, particle size, electrical conductivity, magnetic conductivity and surface properties and other physical properties of the difference to achieve separation. At present, the more widely used are wind shaking technology, flotation separation technology, cyclone separation technology, flotation and sinking method of separation and vortex sorting technology.
