Since the 1960s, the U.S. Bureau of Mines has been recovering precious metals from circuit boards, and now it has been more than half a century. Previous people have studied several more effective recovery methods, such as wet leaching, pyrometallurgy, etc. The treatment of waste circuit boards and the extraction of valuable elements, from the beginning of direct incineration, to direct smelting, to acid washing and electrolysis and biological treatment methods, have their own characteristics but more or less all have certain defects. In this paper, we take dry mechanical automatic treatment as the main means to treat the circuit board, analyze the metal elements in the board and make a plan to realize the effective recovery and reuse of resources. According to the market and customer requirements, the production line of circuit board recycling equipment developed by Runda is an environmentally friendly automatic equipment developed according to the practicality of various types of circuit boards, in addition, Xingmao can provide investors with relevant knowledge of raw materials and the value of various types of metal recycling.
On the other hand, Xingmao machinery to provide customers with automated circuit board recycling equipment production line, the use of disassembly, crushing, crushing, wind selection, gravity separation and high pressure electrostatic separation of the entire technical process to achieve the separation of circuit board metal and non-metal, while completing the extraction process of high purity on the basis of environmental standards. For the use of processing electronic components with high value reuse value considerations, Runda R & D circuit board disassembly equipment is now very mature development, the first example of the entire machine configuration of environmental protection-related water spraying facilities, activated carbon adsorption facilities and dust removal facilities, to meet the strict environmental standards requirements. Automatic circuit board disassembly machine technical standards for the inner tube using six millimeters thick 45 steel plate and the corresponding production technology; with high temperature resistance, anti-wear, * reliable, stable performance, high precision, durable and other characteristics, is the electronic circuit board industry production field indispensable ideal equipment, the circuit board disassembly equipment disassembly principle is through the heating vibration way processing, components and solder at a certain temperature through The role of vibration facilities fall off, due to the components have high temperature resistance characteristics, through the detection of the performance of the components before and after dismantling found that through the electric heating of this method of processing the components of the damage rate is very small, a minuscule only about 3%. Runda circuit board disassembly equipment selection of electric heating ring has good stability, at high temperatures is not easy to oxidation reaction, but also not easy to produce a chemical reaction with the metal. Its heating temperature is appropriate and does not volatilize at high temperatures, non-toxic, so it will not cause secondary pollution to the environment.
