crushing and characterization of particles

A basic guide to particle characterization

3 A basic guide to particle characterization Particles are 3-dimensional objects, and unless they are perfect spheres (e.g. emulsions or bubbles), they cannot be fully described by a single dimension such as a radius or diameter. In order to simplify the measurement process, it is often convenient to define the

Characterizations of macroscopic deformation and particle

Crushing ratio —— At present, the most commonly used quantitative indicator for characterizing the particle crushing degree in geotechnical engineering is the Marsal crushing ratio (B g) . Marsal crushing ratio is defined as the sum of positive values of difference in gradation content before and after the test, which is expressed in Eq. .

Evolution of Friction and Permeability in a Propped

We explore the evolution of friction and permeability of a propped fracture under shear. We examine the effects of normal stress, proppant thickness, proppant size, and fracture wall texture on the frictional and transport response of proppant packs confined between planar fracture surfaces. The proppant-absent and proppant-filled fractures show different frictional strength.
