Analysis for Particle Adhesion Mechanisms during Ball Milling

Abstract

During ball milling, particles sometimes strongly adhere to the surface of grinding balls and the grinding chamber, and this adhesion phenomenon is called sticking. The elucidation of the sticking mechanisms has been one of the most important issues to realize the control of the grinding behavior during ball milling. However, the sticking mechanisms have not been elucidated because particle sticking behavior has difficulty in being analyzed experimentally. Although the simulation techniques have been utilized to analyze such the particle behavior, the particle sticking behavior has not been analyzed because there is no simulation model to represent the motion, breakage, and adhesion of particles. Therefore, in this project, we developed a new simulation model for representing the motion, breakage, and adhesion of particles.
