Henan Doing Environmental Protection Technology Co., Ltd

E waste recycling machine manufacturer




Which types of e waste recycling machine suitable for circuit board recycling business using?

There are different types of E waste recycling machine, such as PCB dismantling machines, PCB crushing and separation production lines, gold stripping machines, precious metal separating and refining machine and copper electrolysis system, which can be used to process circuit boards to extract metal.

Part1:PCB Dismantling Machine

Generally speaking, the circuit board is composed of substrate, electronic components, solder joints, etc. PCB dismantling machine is a matched machine with the PCB crushing separating production line, used for dismantling the electronic components from waste circuit boards, then getting bare circuit boards and electronic components.

The electronic components dismantled can be sold directly for precious metal extraction. Bare circuit boards can be sent into PCB crushing separating production line for further processing to obtain mixed metal and resin fiber.

Part2:PCB Crushing Separating Production Line

This PCB crushing separating production line adapts mechanical crushing and separating technology, which can help you obtain metal, resin and fiber powder from waste circuit boards. PCB crushing separating production line is consists of a shredder, crusher, magnetic separator, air separator, electronic separator and pulse dust collector. Through sufficient crushing and multiple separating, the separating rate of metal can reach 99%.

Except circuit board, this PCB crushing and separation production line is also suitable for processing copper clad laminates, computer motherboards, TV boards, computer boards, mobile phone boards, various waste electrical appliances motherboards, and processing waste, etc.

If you just want to get profit from mixed metal and resin fiber, the PCB crushing separating production line is enough. But if you want to extract gold, you have to add gold stripping machine.

Part3:Gold stripping machine

Gold stripping machine was specially designed to strip gold from gold-plated materials that come from those obsolete and junked electronic products, which is currently the best gold extraction method. By using this machine, the recovery rate of gold is up to 99%, and you can get high-purity gold after further refining.

Gold Stripping Machine applies to various gold-plated scraps generated in our daily life, such as waste cellphone circuit boards, computer CPUs, motherboards, VCDs, DVDs, TVs, game consoles, fax machines, telephone sets and many other old domestic appliances, as well as those leftovers and off-cuts from the electroplating factory, electronic components manufacturing factory, printing house, photosensitive materials plant.

Part4:Precious Metal Separating and Refining Machine

Precious metal separating and refining machine is used for recovery and refining precious metals such as gold, silver, palladium and platinum from circuit board containing precious metal chip components and anode mud.

After dismantling the electronic components can not be returned, such as chip, north and south bridge, storage chip, integrated circuits, field-effect plastic components, etc., which are the highest collective materials containing gold and silver and comply with the unified processing of elements. After ozone baking (ozone can completely destroy the formation of harmful combustion smoke), the soluble carrier is used to roast the residue, leaching copper, tin, gold, platinum and palladium hydrochloric acid leaching medium to extract gold, platinum and palladium.

Part5:Copper Electrolysis System

Copper electrolysis system is used for refine the copper from the mixed metal powder, the purity of finished copper is as high as 99%. The electrolytic copper production is processed in the huge copper electrolytic tank fulfilled with copper electrolytic solution. Even the best chemical method cannot remove all the impurities from the copper, but with electrolytic refining it is possible to produce 99% pure copper.
