As we all know, copper is widely used in various fields. The main application of copper is as an electrical conductor. As such, extremely high purity levels are required to maintain low electrical resistance. It is researched that as little as 0.08% iron will reduce the conductivity of copper by 33%. The following text is mainly to discuss the expected distribution of contaminants in scrap that is introduced into the thermochemical process.
Most impurities in copper scrap dealt with by thermochemical process will tend to be oxidized during processing and removed with the slag. Theoretically, this will include all oxides whose free energies of formation are more negative than that of copper. However, blister copper after processed by thermochemical way is reported to contain small amounts of impurities and precious metals. Therefore, thermochemical is not the most proper way to recycle copper.
In contrast with thermochemical process, mechanical process is a easier and more efficient way for copper recycling. It has two sub branches: Profile cut peeling machine processing method and Roller peeling machine processing method. The former is mainly applicable to thick cables and wire. The later is suitable for scrap wires and cables of same diameter. This method contributes to the comprehensive recollection of copper and plastic, a higher level of comprehensive utilization. Meanwhile, the output of copper does not contain plastic, reducing plastic’s pollution for the atmosphere during melting.
There is no doubt that ace machine will get a better recycling effect. Whirlston, taking the leadership for 12 years, is responsible for providing quality and satisfying copper recycling machine for you. The two main copper recycling machines are copper cable granulator and wire stripping machine. Its copper cable granulator brings you high pure copper granule up to 99.9% and its wire stripping machine are CE certificated.
Good chance is in front of you, don’t miss it! Whirlston is always willing to cooperate with you!
