Henan Doing Mechanical Equipment Co., Ltd will provide you the best solution for PCB recycling with 99.9% recovery rate. The PCB recycling machine adopts dry type physical separation methods to get scrap PCB boards shredded or crushed at first, then separate the metals and nonmetals through air separation and electrostatic separation process, equipped with dust collecting system. The whole PCB recycling process is totally clean and environmental friendly, no fire, no water, no chemical. From the research for normal PCB boards, in which the percentages of the electronic components, base board and soldering tin are 58%, 37% and 5% separately. And for every one ton base boards, it include about 40% metal materials and 60% nonmetals, which contain almost all the common elements in periodic table. By estimate, for 1 ton computer circuit boards, it 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.
