Granulation is conducted to free metals from plastic insulation and jacketing. Fine granulation is necessary to achieve sufficient liberation of metals from the plastic. However, small amounts of metals will remain locked in the plastic and be lost as waste.
Granulation methods can be divided into two types: wet methods, which need liquid in the process, and dry methods in which no liquid is needed. Wet granulation involves a mix of dry copper wire scrap using granulating fluid. The fluid contains a solvent which must be volatile so that it can be removed by drying, and be non-toxic. Typical liquids include water and ethanol either alone or in combination. Water is commonly used for economical and ecological reasons. The main technological process is crushing (with water)—gravity shaker (with water).
In the dry methods of granulation the primary powder particles are aggregated under high pressure. During the sorting process, this kind of copper wire granulator prefers the environment-friendly way, such as, air sorter, air shaker or electrostatic separation. The main technological process is crushing—air flow separating and selecting—(electrostatic separation)—dust collection.
You can choose the dry method or the wet method based on you practical needs. Recycling of copper cables is motivated by the high value of copper. The first step of recycling is to separate the conductor from the insulation and jacketing. The copper is then sent to be granulated.
Copper is amongst the highest valued non-ferrous metals and in ample supply in end-of-life vehicles, transformers, electric cabling and many other sources. To tap into this potential and maximize returns, Zhengzhou Amisy manufacturers and offers the best copper wire granulator and wire stripping machine and all your requirements are met with prompt and individual attention.
