How should the recycling of waste aluminum products be classified

Waste aluminum is a common name for recycled aluminum. After pretreatment, part of the recovered aluminum will be cold-processed to turn it into powder aluminum, while the other part will be recycled by means of heavy medium dressing and parabolic dressing.

For waste aluminum products, the primary classification, classification stacked, such as pure aluminum, aluminum deformation, aluminum casting, mixed materials, etc. The import volume of aluminum scrap accounts for more than one tenth of the country's total import volume. The processing of raw materials is highly computerized, all incoming raw materials are stored in different zones, and the inventory is maintained according to quantity, chemical composition, recovery and cost. This information enables the smelting process to calculate economical formulae for the production of alloy ingots and to ensure product quality.

For waste aluminum products, it is necessary to disassemble, remove steel and other non-ferrous metal parts connected with aluminum materials, and then make waste aluminum materials through cleaning, crushing, magnetic separation, drying and other processes. For the thin and loose pieces of scrap aluminum, such as the locking arm on the car, speed gear shaft sleeve and aluminum chips, to use hydraulic metal baling press into the bag. For steel core aluminum stranded wire, the steel core should be separated first, and then the aluminum wire wound into a coil.
