PARTICLE SHAPE IN THIXOTROPIC SUSPENSIONS

Canadian Journal of Chemistry, 1951
Several equations have been proposed that predict the shape of suspended particles when the viscosity of a suspension of known concentration is measured. These are not applicable to suspensions showing thixotropy, owing to the dependence of the measured viscosity on the shear rate used. However, by using viscosity values that have been extrapolated to

REVIEW OF APPLIED PARTICLE SHAPE DESCRIPTORS AND PRODUCED PARTICLE SHAPES IN GRINDING ENVIRONMENTS. PART I: PARTICLE SHAPE DESCRIPTORS

Mineral Processing and Extractive Metallurgy Review, 2005
The various types of particle shape, morphology, texture, and particle angularity descriptors that are applicable and useful in different grinding methods with respect to various geometric measures existing in image analysis software are presented and reviewed. In addition, some disadvantages of such descriptors are discussed.

Real-Time Shape-Based Particle Separation and Detailed in Situ Particle Shape Characterization

Analytical Chemistry, 2012
Particle shape is an important attribute in determining particle properties and behavior, but it is difficult to control and characterize. We present a new portable system that offers, for the first time, the ability to separate particles with different shapes and characterize their chemical and physical properties, including their dynamic shape ...

Shape Factors for Airborne Particles

American Industrial Hygiene Association Journal, 1971
Shape factors for dry aerosol particles generated from 1% solutions by weight of sodium chloride, uranine, or combinations of these two compounds were measured. A factor was obtained for each aerosol, relating particle projected area diameter to aerodynamic diameter, mass, and resistance to viscous flow. The density of dry uranine aerosol particles was

Dynamic Shape Factors for Particle Shape Characterization

Particle & Particle Systems Characterization, 1985
AbstractThe need for particle shape characterization has been internationally recognised and has resulted in a number of publications proposing a variety of methods for particle shape analysis and shape description. Though very important in chemical engineering, correlations between shape parameters and bulk properties are still rare.This paper ...
