How to recycle PCB circuit board

Why recycle PCB circuit boards?  
From the research for normal PCB boards, in which the percentages of the electronic components, baseboard, and soldering tin are 58%, 37%, and 5% separately. And for every one-ton baseboard, includes about 40% metal materials and 60% nonmetals, which contain almost all the common elements in the periodic table. By estimate, 1 ton computer circuit boards, contains 0.5kg gold, 130kg copper, 10kg iron, 60kg Plumbum, 40kg tin, 36kg nickel, 40kg antimony, and some other rare precious metals, like Platinum, palladium, etc.

How to recycle PCB circuit boards?  
The waste PCB circuit board is separated from the circuit board by the electronic components and solder of the waste circuit board through a PCB dismantling machine. The circuit board after removing the electronic components is shredded into sheet materials by a shredder. It is further processed by hammering and crushed into small pieces of material. The small pieces of material are ground into powder by a mill to achieve the separation of copper and plastic in the PCB. After specific gravity separation, the specific gravity of the material is under the same airflow. The different physical reactions caused by different separations separate copper and plastics. Through electrostatic separation and adsorption, the insulators and non-insulators are separated to obtain the separation of copper and plastics. Pulse dust removal is used to filter the dust in the waste to meet the emission requirements.

Waste PCB Board Recycling Machine
Waste PCB board recycling production line can be used for recycling all kinds of circuit and motherboards including aluminum plastic plate, copper clad board, printed circuit boards and TV boards. The metal is recovered with higher efficiency and the recovery rate is up to 99%. Different kinds of metals and non-metals are present in the scrap which need to be refined and separated and contained in separate containments, which is done by waste PCB recycling equipment.

Working Principle Of Waste PCB Board Recycling Machine  
First of all PCB recycling machinery is rendered to a mixture of metallic and non-metallic powder by two time mechanical pulverization. After it, the mixture is completely separated into metals and non-metals by air separation technique. This complete process is performed in one production line and its fully closed operation ensures avoidance of any kind of pollution and noise.  
Raw materials which can easily be processed by waste PCB recycling machine of the waste PCB recycling production line include waste printed circuit boards equipped with electrical components as well as having no electrical components. It also includes the processing of copper clad plate. Circuit boards come from various kinds of electric equipment including televisions and computers. Green boards come from televisions, communication equipment, computers and other high-value equipment while the yellow board is contained in a tape recorder, audio equipment, air conditioners, washing machines and other low-value equipment.

Characteristics Of PCB Board Recycling Machine  
Following are some significant characteristics of circuit board recycling machine:  
1)It reduces the consumption of power.  
2)It produces very little or no noise thus reducing noise pollution.  
3)It has good performance and completes the recycling process with great efficiency.  
4)It has a unique effect on computer and television circuit boards as it recycles them and leaves the product in a good condition which makes the circuit boards reusable.  
5)It reduces manual power consumption and fastens the recycling and production rate of circuit boards.  
6)It covers a relatively smaller surface area.  
7)It adopts the method of dust catcher which helps to keep the environment clean.  
8)It does not emit any harmful gases or harmful chemicals during the recycling of circuit boards by PCB recycling machine.  
9)It has a neat surface and produces comparatively lower noise than other recycling methods.  
10)It uses high automation procedures and can work a whole day without stopping. This lets processing of a large number of circuit boards in a small time.

The working principle and characteristics of e waste recycling machine and motherboard recycling machine let us know about the benefits and mechanisms which make the recycling process fast and efficient by reducing manpower and pollution as well.
