Back ground of printed circuit board scrap|pcb recycling
The main components of the circuit board (PCB) are substrates and electronic components, and the main components are non-metallic components such as metals, oxides, organics, glass fibers, and epoxy resins. At present, it basically does not contain environmentally sensitive substances and has a certain recycling value.
The metal grade in the circuit board(PCB) is equivalent to tens to hundreds of times that of ordinary minerals. The metal content is above 40%, mainly copper. In addition, there are gold, tin, nickel, lead, silicon and other metals, including rare metals, while the content of rich ore metals in nature is usually only 3-5%. In addition, the non-metallic slag of discarded circuit boards(PCB) can be used as construction raw materials. At the same time, solder and plastic on discarded circuit boards are also important resources that can be recycled. Therefore, the establishment of more and more circuit board(PCB) recycling plants provides a final destination for a large number of discarded circuit boards, and can better protect the environment and their own health.
Description of our printed circuit board scrap|pcb recycling machine
Our circuit boards recycling machine adopts advanced physical recycling process, which can help you obtain metal, resin powder and fiber powder from used printed circuit boards. Copper powder and resin fiber powder can be sold directly in the market, therefore, recycling pcbs can not only bring great economic value, but also protect the environment.
Applications of our printed circuit board scrap|pcb recycling machine
all kinds of pcb raw materials,such as
(a)Computer motherboards, Cell phone boards, Tv Boards,Freezer boards,air-conditioner boards,Radio Boards,Printer boards, overleft of pcb ,Coated copper plate/copper clad laminate.
(b).electronic components, such as capacitance, resistance, potentiometer, relay,etc.
Final output material of the pcb circuit boards recycling machine
Affter we process the circuit boards (pcb) we can obtain metal, resin powder and fiber powder from used printed circuit boards.In addition, the non-metallic slag of discarded circuit boards(PCB) can be used as construction raw materials.
The processing step of printed circuit board scrap|pcb recycling machine
Step 1: Electronic components dismantling
Usually, the first step of circuit board recycling is to separate the electronic components from the circuit boards by using PCB dismantling machine. Then you will get naked circuit mother boards, which will get further processing to get copper powder and resin powder.
Step 2: PCB boards shredding and crushing
Circuit board shredder is the very first machine to size reduce circuit board. Its infeed opening should be big enough to process tons of circuit board at the same time. During shearing and crushing of 2 rotors, circuit boards are broken down into irregular pieces. For the first shredding machine, we choose the double shaft shredder. After circuit board shredding, the particles are around 60mm by 60mm. Next, the second crushing machine is a granulator, resulting in 20mm particles. Then the shredded material is collected in a mesh box and processed further.
Step 3: Separate the metal and non-metal powder
The shredded PCB will be separated by the air separator and the electrostatic separator. Our PCB recycling machine adopts dry type and physical crushing, separation and dedusting methods, which can keep no pollution to the environment. And the high pressure electrostatic separation combined with air separation process, which can purify approximately 99% metal powder.
