With people's demand for products with smart grid, the cable wire manufacturing industry get developed swiftly. However, many waste cable wires are generated in life, with the increasing demand for cables and the upgrading of new and old products.
As we know, most of cable wires are made of copper and PVC. Both of them are recyclable materials, which can bring profit to us. Well, how to separate copper and PVC, which method is the best? Let's have a look.
There are usually four ways to process waste cable wires: burning method, stripping method, wet type separation method and dry type separation method.
The first burning method is to separate copper from PVC through burning the PVC by fire. However, the PVC may be stick to copper, which will affect the purity of copper. And the quality of copper will be damaged. Moreover, the burning will emission harmful gases, which will pollute the environment, as well human health.
The stripping method will use a machine: wire stripping machine. It can strip copper from PVC. But this stripping machine can only process wires with big diameters. Very thin wires can't be processed by this machine. Besides, the wires can not be entangled with each other, otherwise, you need to separate them firstly. Its working efficiency is pretty low.
About wet type separation method, it will crush the waste cable wires into small particles by using crusher, and then use vibrating screen and water to separate copper and PVC. At last, you will get wet copper and wet plastic, then you need space and time to dry them. Moreover, the used water will contain copper ions, which not only cannot be reused, but also pollutes water resources.

As for dry type separation method - it refers to waste cable wire granulator machine, which can separate copper from PVC through crushing and separation. It uses no water, fire, or chemical solution, so it won't pollute the environment. Besides, it has the advantages of wide application, high separation rate, low cost, small footprint, high degree automation, etc.
