Scrap Aluminum Shredder

The scrap aluminum shredder is a specialized pre-processing machine for the metal recycling industry. Typically featuring a dual-shaft or single-shaft, low-speed, high-torque design, it processes bulky and irregularly shaped scrap aluminum (such as aluminum profiles, thermal-break aluminum, beverage cans, aluminum castings, aluminum sheets, and aluminum briquettes). Through shearing, tearing, and crushing actions, it reduces the material into uniformly sized fragments and achieves preliminary liberation of aluminum from attached impurities like iron, plastic, and rubber. As the primary core piece of equipment in a scrap aluminum recycling line, it prepares suitable feedstock for subsequent sorting and smelting processes.

Scrap Aluminum Shredding and Recycling Line:
1.  Feeding: Automatic feeding via a slat conveyor; large items and bundled scrap aluminum are pre-dismantled to ensure continuous, stable equipment operation.
2.  Primary Shredding: A aluminum shredder performs coarse shredding on large scrap aluminum, cutting material into uniform, smaller pieces and achieving preliminary separation of aluminum from composite impurities.
3.  Secondary Crushing & Liberation: Coarsely shredded material enters a metal crusher; high-speed impact fully liberates aluminum from plastic, rubber, and rust, with an integrated dust removal system collecting airborne dust.
4.  Magnetic Separation: Magnetic separation equipment captures ferrous impurities (such as iron and steel) from the material stream.
5.  Air Separation: Airflow-based separation removes lightweight debris, such as dust and plastic film.
6.  Eddy Current Separation: Utilizing the eddy current effect generated by an alternating magnetic field, aluminum is precisely separated from non-metallic waste to yield purified aluminum granules.
7.  Product Collection & Baling: Purified, high-quality aluminum is collected and baled for direct use in smelting, while various impurities are sorted and processed separately.

Process Note: The process can be simplified for clean, impurity-free aluminum profiles by omitting the eddy current separation step; however, complex mixed scrap—such as thermal-break aluminum or material containing rubber—requires the full sorting process to ensure high recovery purity.
