Aluminium oxide primarily used for the production of aluminium; Particle size analysis; Sieving method

This document establishes a standardized method for determining particle size distribution of alumina intended primarily for the aluminum production industry. The procedure relies on sieving techniques, providing a consistent approach for analyzing the granularity of the material. By defining specific operational parameters and equipment requirements, it ensures that measurements are reproducible across different laboratories and facilities. The methodology focuses on separating alumina particles based on their size using a series of sieves with defined mesh openings. This facilitates accurate characterization of the feedstock, which is critical for maintaining process efficiency and product quality in downstream smelting operations. The approach outlined is designed to be applicable for routine quality control and research purposes within the relevant industrial sector. It specifies the necessary precautions for sample handling and the calculations required to interpret sieve analysis results. Adherence to this procedure allows for uniform communication of particle size data among suppliers, manufacturers, and technical auditors. The standardized framework supports the optimization of alumina processing without imposing unnecessary complexity on the testing workflow.
