Lactose smearing in transport lines : a thesis presented in partial fulfilment of the requirements for the degree of Masters in Process Engineering at Massey University [PDF]
, 2002 The smearing of lactose in pneumatic conveying lines, leads to cakes of lactose building up within the lines. This is an undesirable situation as it leads to reduced throughput, caused by the narrowing of the lines and the increase in downtime required ...

Fracture of granular materials composed of arbitrary grain shapes: A new cohesive interaction model [PDF]
, 2016 Discrete Element Methods (DEM) are a useful tool to model the fracture of cohesive granular materials. For this kind of application, simple particle shapes (discs in 2D, spheres in 3D) are usually employed.

The influence of particle breakage on stress-dilatancy relationship for granular soils [PDF]
E3S Web of Conferences, 2019 The influence of particle breakage on soil behaviour is important from theoretical and practical perspectives. Particle breakage changes the internal energy in two ways.

SBG model for particle breakage of rockfills based on fractal gradation equation
Yantu gongcheng xuebao, 2022 Accurately predicting the particle breakage rate and the corresponding gradation changes of rockfills in shearing process is beneficial to revealing their characteristics such as strength, penetration and deformation under complex stress conditions ...

Triaxial compression tests on a crushable sand in dry and wet conditions [PDF]
, 2015 A calcareous sand from the Persian Gulf is subjected to a series of dry and fully drained saturated triaxial shear tests. The samples are prepared at relative densities of 65% and either left dry or saturated. They are consolidated to confining pressures

Role of vibrations in the jamming and unjamming of grains discharging from a silo [PDF]
, 2009 We present experimental results of the jamming of non-cohesive particles discharged from a flat bottomed silo subjected to vertical vibration. When the exit orifice is only a few grain diameter wide, the flow can be arrested due to the formation of ...

Turbulent breakage of ductile aggregates
, 2015 In this paper we study breakage rate statistics of small colloidal aggregates in non-homogeneous anisotropic turbulence. We use pseudo-spectral direct numerical simulation of turbulent channel flow and Lagrangian tracking to follow the motion of the ...

The path to fracture in granular flows: dynamics of contact networks
, 2011 Capturing the dynamics of granular flows at intermediate length scales can often be difficult. We propose studying the dynamics of contact networks as a new tool to study fracture at intermediate scales.

One-dimensional compression of a crushable sand in dry and wet conditions [PDF]
, 2015 This paper presents the results of a series of dry and wet one-dimenional compression tests on a calcareous sand from the Persian Gulf. Calcareous grains crush more easily compared to silica grains, a fact that is mainly attributed to their angular shape

Effect of operating conditions and physico–chemical properties on the wet granulation kinetics in high shear mixer [PDF]
, 2009 The wet granulation process is sensitive to changes in product properties and process variables. The optimal process and formulation are based on the knowledge of the granule growth mechanisms and of the effects of product properties and process ...
