Abstract:
The grinding method has been shown to significantly influence the shape characteristics of ground materials, including properties such as circularity, roundness and aspect ratio. Particle morphology plays a critical role in determining material properties, such as packing density, flow behavior, and surface reactivity, which are essential in various industrial and scientific applications.
This study investigates how different grinding techniques—specifically ball milling and vibrating pulverizer—affect the shape characteristics of ground particles. The material under study is natural volcanic glass, with a particle size distribution primarily within the 120–355 μm range. Shape descriptors, including circularity, aspect ratio, and roundness, were measured by image processing of SEM micrographs.
