Published 2018. High-energy ball milling is a promising and effective technique for the production of aluminium nanoparticles. Elemental aluminium powder of 325 mesh, 99.5% purity is taken for this investigation. A planetary ball mill, PM 100, with tungsten carbide balls of diameter 9.5 mm was used.
The objective of this study is to investigate the effect of operating parameters such as ball loading (J), solid mass fraction (C m), pH of the suspension, and grinding time (t) on particle size distribution for the production of nano mineral particles in a stirred ball mill using response surface modeling. The particle size is arrived at by the method of Rosin-Rammler-Bennett distribution rather than by the average
Background: Miniaturization of nanosuspensions preparation is a necessity in order to enable proper formulation screening before nanosizing can be performed on a large scale. Ideally, the information generated at small scale is predictive for large scale production. Objective: This study was aimed to investigate the scalability when producing nanosuspensions starting from a 10 g scale of
