The whole process of recycling aluminum cans

Cans are commonly used in the packaging of various beverages and sodas, and are disposable products. Discarded after use, in fact, discarded cans can be completely recycled.

The recycling method of cans is divided into 4 steps: 1. Crushing: The shape of the recovered waste cans has been destroyed, and some imported waste cans have been broken into pieces. Therefore, it needs to be broken before removing the surface paint.

2. Paint stripping: loose waste cans (including broken waste cans) directly enter the paint stripping kiln for paint stripping. The paint stripping is processed by a rotary paint stripping kiln. At the beginning, a certain amount of heat energy needs to be added. After reaching a certain temperature, the heat energy mainly depends on the heat released during the carbonization process of the can surface paint. In the rotary paint stripping kiln, the paint layer of the can is carbonized, and the paint layer falls off depending on the self-vibration of the rotating process. The temperature of the rotary kiln is controlled at about 500°C.

3. Packaging: The waste cans are very thin, and the burning loss during the smelting process is relatively large, and some can reach more than 10%. In order to improve the recovery rate of aluminum smelting, it is necessary to minimize the surface area of the waste cans and reduce the burning loss. Therefore, the loose waste cans after decarbonization should be packed and compacted. The packing equipment generally adopts hydraulic packing machine.

4. Smelting: The pretreated waste cans enter the smelting furnace for smelting. Cooled into metal blocks, reworked.

The above is a detailed introduction to the recycling process of scrap aluminum cans. The recycling of cans can not only save resources and realize waste reuse, but also avoid environmental pollution and obtain certain economic effects by recycling waste cans. SUNY GROUP can formulate a complete set of solutions for the recycling of aluminum cans to meet customer needs, output, etc. Among them, equipment such as shredders, carbonization and paint stripping equipment, and packaging equipment have obvious advantages.
