Circuit board production process of a large number of edge materials, end-of-life board recycling is also facing a major problem. Waste printed circuit board is a mixture of glass fiber reinforced resin and a variety of metals, is a typical electronic waste, with the increasing number of waste circuit boards plus the production of circuit boards generated by a large number of edge waste, if not properly treated and disposed of, will not only cause a large loss of useful resources, and will have serious environmental hazards. Waste printed circuit boards as an important component of electronic waste has a high recycling value. Electronic waste recycling and the use of circuit board recycling equipment to implement effective treatment and resource recycling of end-of-life circuit boards.
Recycling of waste electronic circuit boards in the process of metal and non-metallic materials used in the equipment environmentally friendly circuit board recycling equipment, the use of mechanical crushing and electrostatic separation method of processing and recycling of electronic circuit boards of metal and non-metallic materials process. Scrap electronic circuit board sent to the powerful crusher for crushing into small pieces of material, and then sent to the magnetic separator to select the iron impurities sent to the crusher for crushing into small particles of material, and then sent to the fine crusher for crushing, where the metal by crushing the original attached to the surface layer of non-metallic materials and become a separate state, become a mixture of metal and non-metallic materials powder, mixed powder through the ultra-micro classifier to separate part of the The mixed powder is separated from the non-metallic materials through the ultra-micro classifier (the part of the powder accounts for 30-60% of the total amount), and then sent to the high-pressure electrostatic separator for the respective separation of metal and non-metal, and then becomes a finished product for recycling.
Circuit board recycling equipment for the implementation of effective treatment and resource recycling of end-of-life circuit boards, can greatly reduce the consumption of primary resources, reduce environmental pollution, the establishment of resource-saving, environmentally friendly society, the development of a circular economy has a positive role and important significance.
