Wire and cable shredder is a kind of pretreatment equipment for the separation and shredding of old wires and cables. It solves the problem that the old wires and cables occupy space resources and cause serious pollution to the environment. More and more wires and cables, mainly metal wires such as copper and aluminum, are being eliminated due to broken and aging lines, which are highly recyclable. However, many people do not understand why they should recycle old wires and cables. If these copper and aluminum wires can be recycled and then treated accordingly, they will turn waste into treasure and reduce the pollution to the environment. Recycled old wires and cables can be mechanically separated through equipment such as shredders to produce copper scraps, mixtures and plastic fibers, all of which are recyclable materials that can be sold on the market.
