A Guide to Particle Size and Shape Parameters By Image Analysis

2021-04-19Guidebook

Introduction

The particle size and shape greatly affect powder properties, which are used to evaluate product performance. Some examples are the packing density of crushed sands, the grinding effect of abrasives, the engineering properties of granular soils, etc. Various parameters are utilized to characterize the particle size and shape, which are described in this guidebook, with the intention to facilitate the understanding of these abstract concepts and provide a more comprehensive interpretation. These parameters provide insight into your samples and will be useful in new product development, product performance improvement, and quality control.
