Parametric dependence of particle breakage mechanisms

Powder Technology, 2001
Abstract It has been observed that the pattern of particle impact breakage in two-dimensional systems is a result of two mechanisms. “Mechanism I” accounts for the breakage induced by the stresses that appear in unbroken particles. “Mechanism II” breakage is due to the buckling of the Mechanism I fragments.

Modelling of particle breakage during drying

Chemical Engineering and Processing: Process Intensification, 2008
An advanced theoretical drying model of single wet particle is proposed. The temperature profile in both crust and wet core regions is described by partial differential equations with appropriate boundary conditions. A Stefan-type vapour diffusion through the crust pores and its convection to the drying ambient has been assumed.

Particle Breakage of a Crushed Sandstone–Mudstone Particle Mixture

2021
Sandstone–mudstone particle mixture (SMPM) is often used as a main filling material in many agriculture-related and civil engineering works such as in rockfill dams and filling foundations. The SMPM was found crushed seriously since it is mixed with mudstone particles.

Experimental Study of Rockfill Particle Breakage

Advanced Materials Research, 2014
As the high concrete faced rockfill dams construction, grain breakage gradually become the factors that influence the high dam construction which can not be ignored. This text based on the master of rockfill of shuibuya dam as the experimental material, getting and analyzing the particle breakage data under different confining pressure through the ...

Simulation of Spherical Particle Breakage

2014
Abstract Many papers on particle breakage provide qualitative descriptions of changes in particle shape, but do not provide quantitative analysis of changes in the particle shape. The papers that provide quantitative analysis often focus on the case where corners are chipped off of a cubic crystal.

A rigorous breakage matrix methodology for characterization of multi-particle interactions in dense-phase particle breakage

Chemical Engineering Research and Design, 2012
Abstract Broadbent and Calcott's breakage matrix methodology has been used for more than 50 years to model various comminution processes and to determine breakage functions from experimental data. The methodology assumes first-order law of breakage and neglects mechanical multi-particle interactions that are especially prevalent in dense-phase ...

Effect of particle breakage conditions on child particle aspect ratio

Powder Technology, 2019
Abstract In particulate processes, the goal is often to control the particle size and aspect ratio distributions. One common unit operation is solution crystallization in agitated vessels, where a rotating impeller can break newly formed crystals. This study used sodium chloride crystals in three sets of laboratory scale experiments to investigate ...

Statistics of multiple particle breakage accounting for particle shape

AIChE Journal, 2004
AbstractA method is presented for developing multiple particle breakage distribution functions that include the shape factor, as well as the particle size. The technique is to first develop a joint probability distribution that accounts for the size and shape factor of each child particle.

Entropy concept to explain the particle breakage

2009
The well-known theories do not explain/predict the tendency of particle breakage for initially concave grading curves. The paper presents the results of some particle breakage initially concave moreover with initially A<0.5 grading curves. The tendency seems to be the same for these.
