E-waste recycling line is also called e-waste recycling equipment, mainly to deal with the abandoned no longer used electrical or electronic equipment, including refrigerators, air conditioners, washing machines, televisions and other household appliances and computers and other communications electronics and other electronic technology out of the product. These raw materials through mechanical equipment shredding, crushing, grinding, separation and other processes, screening out valuable metal recycling, from raw materials to finished products need a series of mechanical equipment, these machines called e-waste production line!

Features of e-waste recycling equipment
- The whole assembly line adopts PLC intelligent programming automatic control and man-machine interface touch screen to realize the uniform feeding and coordination of the whole production line.
- Compact structure, reasonable layout, stable performance, noise reduction processing for crushing equipment.
- The crushing part adopts shredding, crushing and crushing process, and the inside and outside of the crushing chamber adopts circulating water cooling.
- Adopt negative pressure feeding system and pulse dust removal system to purify the working environment.
- The sorting part adopts the combination of proportional sorting and static fine sorting to make the metal recovery rate up to 99%.
Why is it important to recycle e-waste?
E-waste, also known as e-waste, generally refers to used refrigerators, washing machines, air conditioners, TVs, cell phones, computers, hard drives, CD-ROMs, etc. As the electronics market continues to boom, the turnover rate of electronic products such as smartphones, tablets, refrigerators, washing machines, desktop computers and TVs is accelerating. Studies show only 17.4% of e-waste was collected and recycled in 2019. This means that gold, silver, copper, platinum and other high-value, recyclable materials are mostly dumped or incinerated.
E-waste usually contains large amounts of lead, chromium, mercury and other toxic substances, which are highly polluting and harmful. If improperly disposed of not only cause waste of resources, but also bring great environmental pollution, and even a direct threat to human health. At the same time, electronic waste is rich in gold, silver, copper and a large number of precious metals, contains a huge economic value. Through “crushing – disassembly – sorting” and other specialized disposal, can be sorted out copper, aluminum, plastic, rare precious metals and other renewable resources. Therefore, the use of efficient and environmentally friendly recycling methods to achieve resource reuse has become a major trend, and this treasure is attracting more and more attention.
Electronic waste recycling process
Because e-waste contains a variety of materials, including plastics, glass and metals, recycling e-waste requires several steps to recycle these resources in the most efficient way. In general, both manual and automation are involved in the e-waste recycling process. The use of automated equipment in the recycling process contributes to the efficient recovery of reusable materials, the elimination of hazardous waste, and the protection of workers and the environment.
Step 1: Manual sorting and separation
Electronic items are manually sorted, and components that should not be shredded or crushed are removed by hand, such as batteries, UPS battery systems, toner cartridges, and fluorescent lights.
Step 2: Shredding
An Initial Size Reduction step shreds the electronic items into small 100mm size pieces, and a Secondary Size Reduction step further breaks down materials into even smaller fragments that are well suited for the separation process.
Step 3: Magnetic removal
Steel and iron fragments are removed by magnets.
Step 4: Metallic and nonmetallic separation
Other metals, such as aluminum, copper, and brass are separated from non-metallic materials, such as glass and plastic. Separation occurs through Eddy currents, optical identification, and magnets.
Step 5: Separation by water
Plastic and glass are separated by using water. Lead-containing glass may be sent to lead smelters to be used to make new products such as batteries, new CRTs, and x-ray shields. Plastics are separated by color and sold to plastic recyclers.
Once the raw materials are separated, they can be sold as commodities to recyclers and manufacturers to make new electronic devices or other items. Circuit boards are ground up and melted, gases are collected, and metals can be sold as raw commodities. The wood from the old TV model cabinets can be chipped off and used for biofuel burning.
