What should be paid attention to in the recycling of scrap copper-Scrap copper classification
Whether it is for waste lithium-ion battery recycling, why should discharge copper be recycled, or waste wire and cable waste copper treatment, the classification of waste copper must be very clear, otherwise it will suffer losses, especially in market transactions.
There are two types of scrap copper according to its source, one is new scrap copper, which is the waste generated in the production process of copper industry. The metallurgical plant is called "the factory's scrap copper" or "return copper scrap". Scrap scraps from copper processing plants and those returned directly to supply plants are called "industrial scrap", "spot scrap" or new scrap. The other type is old copper scrap, which is discarded after use, such as discarded or dismantled copper scrap from old buildings and transportation systems.
The classification of scrap copper can also be determined by the copper content. Motor copper, that is, the copper on the motor in the motor, the pure copper content is generally 92-94%. Bright copper is the scrap copper that is directly seen. There are No. 1 copper and No. 2 copper. There is also purple miscellaneous copper, including copper scrap, smelted copper, purple miscellaneous copper, burning copper, etc. The copper content is about 80%. Another kind of copper is yellow miscellaneous copper, which contains copper and zinc, and the proportion of pure copper is lower than that of purple miscellaneous copper.
New scrap copper accounts for more than half of the scrap copper used for regeneration. After reprocessing, about 1/3 of all scrap copper is returned to the market in the form of refined copper, and the other 2/3 is reused in the form of non-refined copper or copper alloy. . The premise of direct application of scrap copper is strict classification and stacking and strict sorting. For copper recovery in waste wire and cable, the use of SUNY GROUP copper rice machine has the advantages of simplified process, simple equipment, high recovery rate, low energy consumption and low cost.
Various waste wires and cables such as waste wires and cables from the demolition of buildings can be separated and recycled by a copper rice machine to obtain copper and wire skins, which can be used for secondary use and create higher value. The copper rice machine consulted Riseke Machinery to provide A complete set of scrap copper recycling process and equipment.
