The scrap circuit board crushing and recycling production line is a complete set of production equipment that tears and decomposes scrap circuit boards, their scraps, wires and cables, etc. into copper metal and plastic non-metal. This production line has the characteristics of environmental protection, high output, full automation, high efficiency and energy conservation, and small footprint. The entire line is completely mechanically and physically separated without adding any chemical additives, and a pulse dust collection system is used throughout the process, which will not cause secondary pollution to the environment; It has a unique effect on wires and cables, various circuit boards, and circuit board scraps, with a particularly high copper metal recovery rate.
