How to realize metal recycling of waste circuit boards

Time:2020-07-21 15:18 Author:Suny Group

Waste electrical circuit boards contain more metals, and their comprehensive utilization value is greater, but it is difficult to recycle waste circuit boards. At present, in some areas such as Guangdong, there are special people who recycle waste circuit boards and extract the precious metals in them chemically. However, the pollution to the environment is great. As the country has increased its efforts to control environmental pollution projects, the old-fashioned recycling and treatment methods of waste circuit boards have not adapted to 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 just break the circuit boards to separate the metals and non-metals. The important thing is that it is the key technology that can separate the metal and non-metal powders through scientific and reasonable technological methods; the usual traditional process is to first smash the mixed powders with different particle sizes after sieving into approximately equal particle sizes. , And then according to the different proportions of the materials, the principle and method of gravity air separation are used to separate different kinds of materials; although this process method can be used in the recycling and processing of waste circuit boards, due to the complex process and high energy consumption , Low efficiency, large equipment investment, therefore, from an economic point of view, it has certain limitations.

In order to overcome the complexity of the above-mentioned traditional classification and separation process, SUNY GROUP environmental protection has modified the internal structure of the crusher on the basis of absorbing the advantages of the traditional process, and combined the two processes of crushing and winnowing separation into 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 all aspects of the process and technical indicators have been significantly improved and improved, forming our own unique process treatment method.

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

SUNY GROUP environmental protection circuit board recycling equipment has advanced physical recycling technology, equipped with crushers and high-voltage electrostatic separation equipment, which are innovative, and the resource-based treatment process is advanced and reasonable. The circuit board shredder equipment can process all kinds of waste circuit boards, computer boards, TV boards, aluminum-plastic panels, copper clad laminates, and printed circuit boards, so as to reduce and recycle various types of solid waste and electronic waste. Harmless, environmentally friendly, turn waste into treasure, and make efforts for environmental protection.
