What is Particle Size Distribution D50, D50 Particle Size ...

2021-10-23  Particle Size Distribution D50 is one of an important parameter characterizing particle size. For example, if D50=5.8 um, then 50% of the particles in the sample are larger than 5.8 um, and 50% smaller than 5.8 um. D50 is usually used to represent the particle size of group of particles.

FDEM Simulation of Rocks with Microstructure Generated

2019-11-30  Rock strength variation is closely related to its microstructure. With the development of computer technology, the numerical model of rocks can be constructed via computer programming, and the numerical simulation avoids a mass of redundant experimental tests and usually limited by the samples retrieved from the sub-surfaces. In previous studies, the microstructure in the numerical

Fractal and Morphological Characteristics of Single Marble ...

Crushing of rock particles is a phenomenon commonly encountered in geotechnical engineering practice. It is however difficult to study the crushing of rock particles using classical theory because the physical structure of the particles is complex and irregular. This paper aims at evaluating fractal and morphological characteristics of single rock particle.
