At present, the main technology for the comprehensive utilization of waste wires and cables is mechanical treatment technology. The mechanical processing technology is the main technology adopted by various processing enterprises at present.
It is to use machinery to separate the copper core and plastic sheath of waste electric cables and recycle the copper in them. The commonly used mechanical recycling technologies include wire stripping and crushing, and the machines used are wire stripping machines and granulators.
How to recycle waste cables, how much you know about recycling cables, inaccurate storage methods of waste cables will affect the performance of cables, reduce the life of cables, and affect the price of waste cable recycling.
Now, in view of the storage knowledge of waste cables, let me tell you about the process of recycling waste cables, the process of recycling and processing scrap copper prices of waste wires and cables, and the recycling of cables in various building facilities. When renovating and rebuilding, because of demand, The cable wires need to be re-routed, and the previous cables are just useless.
It is understood that the price of wire and cable recycling is not low, and the purchase of new cables still requires a large amount of money. If the previous cables are recycled in time, it can also bring a lot of considerable income to your company to offset the purchase cost of new cables.
The crushing technology is to directly crush the waste wires and cables into granules by cutting or crushing mechanical equipment and then separating the plastic and metal through the sorting equipment. The complete set of mechanical equipment including crushing and sorting is often called a copper cable granulator.
The inside of the cable is mainly composed of pure copper wire. Because the copper of the cable wire is reddish, this copper is commonly known as red copper.
Red copper has better conductivity, so it will be used to make power cables. In addition, there are brass, copper, bronze, etc. are impure copper, which contains zinc, tin, or phosphorus. This copper is not as conductive as pure copper, so it can only be used to make various structural parts such as copper water pipes or copper handles. such as.
The power cable is very thick. In order to ensure the service life of the cable, the very thick cable is usually composed of several relatively thin cables side by side. The inner cable is covered with a layer of polyethylene insulation, and these thinner cables It is made of many strands of pure copper wires twisted together.
The aluminum copper cable granulator adopts the sorting method without adding water during the sorting process, and mainly adopts airflow sorting or electrostatic sorting methods for sorting. At present, the granulator in China's domestic market adopts two-stage crushing + airflow sorting + electrostatic sorting.
In the traditional copper cable granulator, the diameter of the metal conductor is the same as the distance between the cutters, that is, the waste cables with a single line type, but the state of the cables, in reality, is messy, and the crushing equipment will cause irregularities in the cutter when processing messy wires. Necessary wear, difficult crushing, and low crushing efficiency.
Because power engineering or the power industry is very particular about the use of cables, cables with poor performance or low-quality cables will definitely not be used. Generally, very high-quality cables are used. This type of cable There will be very strict technical standards during production and manufacturing.
The produced wires can be recycled whether they are internal conductive materials or external insulating materials. Moreover, such cables are generally recycled in large quantities at one time.
