Development of Water Atomization System for the Production of Aluminium Powder from End-of-Life Aluminium Metal in Nigeria

Article Preview

Abstract:

This paper reports the complete setup of water atomisation machine designed to manufacture aluminium powder out of discarded aluminium metal in Nigeria. It is a study that evaluates the country’s dependence on imported aluminum powder and the economic effect its has on the country. The specially designed atomizers with high-pressure water supply, atomising nozzles, and tanks turn discarded aluminum scrap into powder in 45 seconds. The studies consist of iterative design optimization and parameter tuning, 82% conversion and aluminium powder manufactured with desired properties.Finite element analysis (FEA) checks the structure for integrity at high pressures; and computational fluid dynamics (CFD) analysis explains thermal dynamics. The results are positive for the domestic aluminum market as it offers a long-term and affordable alternative for aluminum powder production.
