How to effectively recycle e-waste?

Time:0000-00-00 00:00:00 Author:Suny Group

What does e-waste contain? Contains discarded electrical appliances or electronic equipment that are no longer used, mainly including refrigerators, air conditioners, washing machines, televisions and other household appliances, and computers and other communication electronic products and other electronic technology obsolete products. Especially in printed circuit boards, the most common metal is copper, in addition to gold, aluminum, nickel, lead, silicon, etc., among which there are many rare metals.

e-waste

Electronic waste recycling production line: through related equipment, the electronic waste (waste circuit board) is sorted and disassembled, and then crushed, sorted and recycled to obtain precious metals and resin powder.

Circuit board dismantling equipment: The circuit board dismantling equipment production line is a new generation of PCB component automatic splitting machine newly developed by our company. This equipment has a high degree of automation and replaces the disassembly of personnel. It has automatic disassembly function and automatic dust removal function, shortening Dismantling time and small footprint. This equipment is composed of a desoldering furnace, automatic dismantling, automatic dust extraction, conveying platform, and electric control parts. It is an ideal device for dismantling circuit board components.

Automatic Components Dismantling Machine

The characteristics of the circuit board dismantling equipment: The equipment can be operated continuously, and the disassembly efficiency is high. It can automatically sort and recycle the electronic components and solders on the discarded circuit boards at one time; the electronic components are not damaged after dismantling, and can be used continuously. Extend its service life and increase profit margins.

1. The disassembly process is highly automated, reduces labor intensity, and saves manpower and time;

2. Using hot air circulation heating method, the furnace temperature uniformity is good;

3. Temperature controllable and complete functions;

4. The running speed of the conveyor system mesh belt is continuously adjustable;

5. The equipment runs stably and reliably, and the operation, use and maintenance are simple and convenient;

6. Adopt the integrated structure of electric control and furnace body, effectively use the space position, occupy a small area, the equipment structure layout is reasonable and compact, and the appearance design is beautiful and generous;

7. The discharged waste gas is treated centrally, and is adsorbed and filtered to meet environmental protection standards.

Circuit board crushing and sorting equipment: used for processing waste circuit boards, copper clad laminates, circuit boards and scraps and other materials in the separation of metals and non-metals, and then reuse the copper and resin powder.

ZY-BRB Circuit Board Recycling Line

work process:

The waste circuit board crushing and sorting equipment adopts a double-shaft shredding machine for the first breaking machine, a hammer crusher for the second breaking machine, and a high-speed turbo-type shredder for the third breaking machine. The materials are pulverized into powder through three-stage pulverization, and then sorted by air-flow sorting equipment and electrostatic sorting equipment. The structure of this production line is novel and unique; the production capacity is large and the power consumption is low; one feeding is completed by multiple machines in cooperation; the entire 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. Through the separation and sorting equipment, the recycling rate of copper in the waste circuit boards is as high as 99%, which is the first in China.

Waste circuit board crushing and sorting equipment adopts primary shredding, secondary crushing, and tertiary crushing to make waste circuit boards into a mixture of metal and resin fiber powder; then the process route of separating metal and resin by wind and electrostatic separation . In order to prevent dust pollution during processing, a cloth bag dust removal device is added after the wind sorting process, which effectively solves the problem of dust pollution.
