How to realize the metal recycling of waste circuit boards?

Circuit boards in electronic waste are an important part of the recycling process, because waste circuit boards contain more metals, and their comprehensive utilization value is greater, but it is difficult to recycle waste circuit boards. Now, in some areas, there are special people who recycle waste circuit boards to extract the precious metals in them by chemical means, but the pollution to the environment is relatively large, and the old-fashioned recycling and processing methods of waste circuit boards are no longer suitable for the development of society. So, how does the circuit board recycling equipment realize the metal recycling of waste circuit boards?

The purpose of recycling and processing waste circuit boards is to separate the metals and non-metals contained in them, so that the renewable resources can be fully utilized; it is not enough to break the circuit boards to separate the metals and non-metals. The key technology is to separate the metal and non-metal powders through scientific and reasonable process methods; the usual traditional process is to first sieve the mixed powders with different particle sizes after crushing into approximately equal particle sizes. , and then according to the specific gravity of the material, the principle and method of gravity air separation are used to separate different types of materials; although this process method can be applied to the recycling and processing of waste circuit boards, due to the complexity of this process, the energy consumption is high. , low efficiency, large equipment investment, therefore, from an economic point of view, it has certain limitations.

In order to overcome the above-mentioned complexity of the traditional classification and separation process, SUNY GROUP, on the basis of absorbing the advantages of the traditional process, reformed the internal structure of the pulverizer, and combined the two processes of pulverization and air separation in one equipment. In this way, not only the production process is simplified, the equipment investment is reduced, and the production cost is reduced, but also the process and technical indicators in all aspects have been significantly improved and improved, forming our own unique process method.

The entire circuit board recycling equipment processing production line has been systematically optimized. The process is: first, the waste printed electronic circuit boards are smashed to a powder particle size that can peel off the metal, and then the metal and non-metal in the circuit board are separated by physical methods. The metal powder is separated, and the metal powder is further processed or sold directly to customers according to different needs; the non-metallic powder can be directly used as a plastic filling modified material and an active powder material after being processed by a special process. use value.

The environmentally friendly circuit board recycling equipment developed by SUNY GROUP has advanced physical method recycling process, and its equipped crusher and high-voltage electrostatic separation equipment are highly innovative, and the resource-based treatment process route is advanced and reasonable. The circuit board shredder equipment can process all kinds of waste circuit boards, computer boards, TV boards, aluminum-plastic boards, copper clad laminates, and printed circuit boards, so that all kinds of solid waste and electronic waste can be reduced, recycled, Harmless, environmentally friendly, turning waste into treasure, and making efforts for environmental protection.
