Secondary aluminum smelting turns aluminum scrap into aluminum that can be used and recycled repeatedly in a closed-loop process. It offers environmental and economic benefits in terms of reduced landfill waste, greenhouse gas emissions, and energy consumption (recycling a ton of aluminum requires only 5% of the energy used to refine primary aluminum from bauxite ore), thus making the secondary aluminum environmentally sound and economically viable. Because aluminum scrap comes from various sources, the presence of impurities requires preliminary operations and treatments (including sorting, comminution, and thermal treatments) to improve the scrap quality in terms of metal yield and recyclability. In particular, the ability to decoat aluminum, typically through a rotary kiln, improves the process by reducing metal losses and allowing the use of a broader range of scrap. Magaldi tailored its conveyor technology to support the decoating process. Specifically, the Ecobelt® conveyor is designed to transport hot shredded scrap from the decoating kiln to the melting furnace. In the case of multiple furnaces, the integrated flow rate detection system determines the total shared rate and distributes it to each served furnace through a special diverter valve.
