Environmentally friendly electronic waste recycling equipment – the effect of separating metals reaches 99.9%
The large-scale dry production line for waste circuit boards is mainly used for the separation of metals and non-metals in materials such as waste circuit boards, copper clad laminates, circuit boards and scraps. The structure of this production line is novel and unique; the production capacity is large, the power consumption is low; the multi-machine cooperation is completed in one feeding; the production line is fully automatic control. The successful development of this machine not only improves the quality of recycled copper, but also prevents secondary pollution. After separation and sorting equipment, the recovery rate of copper in waste circuit boards can reach more than 99%, which is the first in China.
This production line takes one-time crushing of waste circuit boards in raw processing to make them a mixture of metal and resin fiber powder; and then separates metal and resin through wind and electrostatic sorting. In order to prevent dust pollution during processing, a polyester knitted felt type dust removal device is used after the air separation process, which effectively solves the problem of dust pollution.
Computer program-controlled circuit board recycling equipment is aimed at all kinds of waste circuit boards, circuit boards, PCB boards, FPC boards, circuit board scraps, aluminum-plastic boards, waste TV boards, various waste home appliance circuit boards, waste circuit boards and other waste electronic products. Mechanical crushing and recycling, rationalizing and improving the crushing, crushing, and separation systems of the original circuit board recycling equipment, and being compatible with circuit boards containing electronic components, no need to dismantle electronic components, and circuit boards containing electronic components can be directly After entering the crushing and crushing system for processing and production, the metal recovery rate is higher, and the recovery purity of the metal is as high as 98.5% or more.
The computer program-controlled circuit board recycling equipment adopts a process route of dry crushing and pulverization, so that the raw materials such as circuit boards are crushed and smashed into a mixture of metal and resin fiber particles and powder, and then the metal and resin and other non-metals are separated by a high-voltage electrostatic separator. In order to prevent dust pollution during processing, this equipment also adopts a three-in-one dust removal device (ie, a three-in-one dust collector) independently developed by our company. This dust removal device has three levels of dust removal: cyclone dust removal, bag dust removal and air purifier. Dust removal effectively solves the problem of dust pollution.
