Comparison of Geometric Properties of Regular and Irregular Mineral Grains by Dynamic Image Analysis (2D) and Optoelectronic Analysis (3D) Methods

Autor: Aldona Krawczykowska, Tomasz Gawenda, Damian Krawczykowski

Publikováno v: Minerals; Volume 12; Issue 5; Pages: 540

The properties of bulk materials are influenced by geometrical features of grains such as size, size distribution and shape. However, size is an ambiguous parameter for non-spherical particles. Therefore, the influence of the shape of a particle on i
