This step is the core of the paint stripping process, which separates the paint from the metal through high temperature.

Oil and gas treatment:

Oil and gas dust removal: The oil and gas generated during the paint stripping process are purified by the oil and gas dust removal device to remove impurities in the oil and gas, ensuring that the exhaust gas discharged meets environmental protection standards.

Cooling and sorting:

Cooling: The can fragments that have been stripped are refrigerated and cooled by the automatic discharging device to prevent the aluminum alloy from continuing to oxidize at high temperatures.

Sorting: The cooled fragments are sorted to obtain pure aluminum alloy and other recyclables.

II. Equipment features

High efficiency: The waste can paint stripping equipment line can operate continuously, with a large processing capacity, which greatly improves the recycling efficiency of waste cans.

Environmental protection: No chemical reagents are required during the paint stripping process, avoiding wastewater and exhaust gas pollution. At the same time, the oil and gas generated during the paint stripping process are recycled and reused through the oil and gas recovery system, realizing the recycling of energy.

High degree of automation: The equipment adopts an automated control system, which reduces manual operation links and reduces labor intensity. At the same time, automated control also improves the stability and reliability of the equipment.

Wide scope of application: In addition to waste cans, the equipment can also be used to process other types of scrap metal materials, such as waste cars, waste electrical appliances, etc., and has a certain degree of versatility.
