Circuit board recycling and decomposition equipment extracts waste circuit board metal

Time:2021-06-28 11:50 Author:Suny Group

It has long been heard that the precious metal gold is extracted from the circuit board after recycling and decomposition, and it is true. This shows the value of waste circuit boards, let's talk about the precious metals in the circuit boards first. After processing, it was found that the circuit board contained gold, silver, palladium, platinum, and copper, which is why we need to disassemble and recycle. The precious metals inside can be extracted, and the resources can be reused, creating more possibilities!

ZY-BRB Circuit Board Recycling Line

The method of dismantling and recycling is not difficult in terms of current technology. The whole production process of the circuit board crushing and sorting equipment is: the first crusher adopts a double-shaft shredder, the second crusher uses a hammer crusher, and the third crusher uses a high-speed turbine crusher. The materials are pulverized into powder through three-stage pulverization, and then sorted by air-flow sorting equipment and electrostatic sorting equipment. In order to prevent dust pollution during processing, a bag dust removal device is added after the wind sorting process, which effectively solves the problem of dust pollution. The advantages of this production line are: novel and unique structure; large production capacity and low power consumption; one-time feeding and multi-machine cooperation; the whole production line is controlled by PLC. The successful development of this machine not only improves the quality of recycled copper, but also prevents secondary pollution. The efficiency of the pulse dust removal equipment is as high as 99%, which effectively suppresses the volatilization of dust, and fully meets the national environmental protection requirements "Comprehensive Emission Standard of Air Pollutants" GB16297-1996. The waste circuit board crushing and sorting equipment adopts a one-time tearing process for the recycling and processing of waste circuit boards. Crushing, secondary crushing, and tertiary crushing make it into a metal and resin fiber powder mixture; then the metal and resin are separated by wind and electrostatic separation. The technology is very mature and can withstand the test of the market.

Circuit board recycling and decomposition equipment is also known as waste circuit board crushing and sorting equipment. It is used to process waste circuit boards, copper clad laminates, circuit boards and scraps and other materials in the separation of metals and non-metals, and reuse the copper and resin powder in them. The entire production line has a compact structure, reasonable layout and low noise. The high-voltage electrostatic sorting machine makes the sorting more refined and efficient, and effectively controls the loss of non-ferrous metals. Bridges and guardrails are set up at the height of the whole production line to facilitate the maintenance personnel to monitor and maintain the equipment in real time, which is safer and more environmentally friendly.
