Circuit board recycling equipment establishes those norms when it comes to e-waste recycling

With the progress and development of society, the widespread popularization and rapid updating of electronic products such as waste home appliances, mobile phones, televisions, computers, air conditioners, etc., make e-waste a social problem that has received more and more attention. The harmless treatment of electronic waste recycling and processing has become one of China's environmental protection efforts. The circuit board recycling equipment mainly processes various waste circuit boards, circuit boards, copper clad laminates, leftovers, aluminum-plastic panels, waste sheets, electronic components, etc. Circuit board recycling equipment can not only separate metals from various metal wastes, but also recycle various waste circuit boards.

Most of the circuit board recycling equipment are mature in technology and belong to large-scale industrial production, while most of the others belong to small stand-alone and small batch production. These processing equipment have defects such as high energy consumption, low production capacity, incomplete separation after pulverization, and large fineness range, which makes the gravity separation rate lower than 90%. Due to their high production cost, high labor intensity and unsatisfactory economic benefits, these technologies cannot be industrialized. At present, there are many circuit board recycling equipment used in China. For the rare or precious metal part of the circuit board, crushing separation is adopted, that is, the precious metal is left after removing other components. There are no three wastes in this process, which can ensure environmental protection measures, no harm to the environment and workers, and effective use of these resources.

The circuit board recycling equipment crushes the waste circuit boards to less than 2 mm, then removes iron through magnetic separation, and uses high-voltage electrostatic separation technology for separation, so as to realize the recycling of resources. For example, the electronic components, glass, colloid, stainless steel, copper wire, copper sheet, aluminum, rubber, plastic and various iron contained in the circuit board can directly enter the equipment for separation and sorting without removing, and the metal recovery rate can reach More than 99%. The process can be automatically operated by only 1-2 people from feeding to sorting. The process is physical dry separation, does not require heating, incineration, water and chemical raw materials, low cost, high efficiency, and no environmental pollution at room temperature dry separation. Circuit board recycling equipment has established norms in e-waste recycling, injecting new impetus into environmental improvement, and the e-waste recycling market will usher in new vitality.
