Method for separating metal and plastic from waste circuit board recycling equipment

2020-07-10

Printed circuit boards are an important part of electronic and electrical products. With the continuous upgrading of electronic products, at least hundreds of thousands of tons of waste printed circuit boards are produced every year. Waste circuit boards are mainly made of organic reinforced resin, glass fiber, copper foil It is composed of electronic components, which contains a lot of valuable metals (such as copper, iron, aluminum, tin, etc.) and has a high value for resource recovery.

2020 environmentally friendly new circuit board recycling and processing equipment effectively realizes the harmless recycling of waste circuit boards and realizes their recycling. It can reduce environmental pressure and prevent environmental pollution, improve the recycling rate of secondary resources, and ensure China’s economy, society and environment. Sustainable development has very important significance. Reasonable separation production process of waste circuit board recycling equipment: raw materials are used to shred, rough break, crush, air separation, vibration separation and separation, environmental protection treatment and other processes, and can be recycled to copper-based metal mixtures and non-metal Metal powder mixture; the dust and waste gas formed during the process are collected in an orderly manner and uniformly subjected to dust removal and waste gas purification treatment, and discharged to the air after environmental protection reaches the standard.

The recycling process of mechanical crushing and electrostatic separation of the waste electronic circuit board includes crushing the waste electronic circuit board, further crushing after iron removal, and then finely crushing, firstly separating some non-metallic objects through the ultramicro classifier, and then being sent into The high-voltage electrostatic separator separates the metal and the non-metal and becomes the finished product recovery.

With the updating of the information age, the circuit boards, capacitors, etc. in various smart appliances have been gradually replaced, and these discarded electronic components have been recovered by specialized personnel, of course, because it still has a certain surplus Of value, an important value is that the metal waste electronic components contained in electronic waste are not garbage, but effective resources. The electronic component waste crushing treatment equipment can conveniently separate the circuit board and the component, and then crush the circuit board to achieve the purpose of recycling some components.
