The material of cans is aluminum alloy, which is a very important metal resource. Since the 20th century, countries around the world have paid more and more attention to environmental protection and circular economy, and sustainable development has become the mainstream. Therefore, the recycling of cans has important social significance and economic value.
The can recycling method is divided into 4 steps:
1. Shattering: The shape of the recovered waste cans has been destroyed, and some imported waste cans have been broken into lumps. Therefore, they need to be broken before removing the paint.
2. Paint stripping: loose waste cans (including broken waste cans) directly enter the paint stripping kiln for stripping
paint. The temperature of the rotary kiln is controlled at about 500℃;
3. Baler: The waste cans are very thin, and the burnt loss during the smelting process is 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 cans after decarbonization should be packed and compacted. Baler equipment can adopt the professional can Baler of Nick Machinery;
4. Smelting: The pre-treated waste cans enter the smelting furnace for smelting.
Two very important steps in the can recycling process are crushing and Baler. The two-shaft crusher and metal baler produced by Nick Machinery provide equipment guarantee for the can recycling process. For more information, please refer to Nick Machinery's website www.nkbaler.com.
