Scrap aluminum recycling equipment
1. Scrap aluminum shredder: used to break scrap aluminum products, such as aluminum wheels, aluminum profiles, aluminum foil, etc. into small pieces or particles for subsequent recycling and processing. There are many types of scrap aluminum shredders, such as shearing type and hammer type, and suitable equipment can be selected according to different scrap aluminum products.
2. Magnetic separator: used to separate iron impurities from the crushed scrap aluminum to ensure the purity of the recycled aluminum products. The working principle of the magnetic separator is to use the attraction of the magnetic field to the iron material to separate it from the mixture.
3. Eddy current separator: used to separate non-ferrous metals and non-metallic materials, such as plastics, rubber, etc. from scrap aluminum. The working principle of the eddy current separator is to use the eddy current generated by the conductor in the high-frequency alternating magnetic field to make the conductor repulsive and achieve separation.
4. Scrap aluminum crushing and recycling line: including hammer crusher, magnetic separator, eddy current separator and other equipment, through a series of automated processes, the scrap aluminum is crushed, separated and purified to improve the purity and efficiency of scrap aluminum recycling.

Scrap aluminum recycling process:
1. Pretreatment: The collected scrap aluminum is preliminarily sorted, cleaned and cut to remove impurities such as explosives, iron parts and moisture. The purpose of this step is to facilitate subsequent crushing and separation operations.
2. Crushing: The pretreated scrap aluminum is sent to the scrap aluminum shredder for crushing. The crushed scrap aluminum particles are of moderate size, which is convenient for subsequent separation and purification operations.
3. Magnetic separation: The crushed scrap aluminum is separated from iron impurities by a magnetic separator. The magnetic separator can effectively remove iron substances such as iron nails and iron wires in scrap aluminum, and improve the purity of recycled aluminum products.
4. Eddy current separation: The scrap aluminum after magnetic separation is separated into non-ferrous metals and non-metallic substances by an eddy current separator. The eddy current separator can accurately separate non-metallic substances such as plastics and rubber from scrap aluminum, further improving the purity of recycled aluminum products.
5. Refining and alloy blending: For aluminum alloy products that need to produce specific grades, the recycled scrap aluminum also needs to be refined and alloy blended. The purpose of this step is to remove impurities and gases in the scrap aluminum, and add alloy elements as needed to meet production requirements.
