A microlevel-based characterization of granulation phenomena

BJ Ennis, G Tardos, R Pfeffer - Powder Technology, 1991 - Elsevier
Past granulation research has been essentially restricted to a macroscopic study of the
impact of operating variables on granule morphology. While fundamental groundwork …

High-shear granulation: An investigation into the granule consolidation and layering mechanism

SAL de Koster, K Pitt, JD Litster, RM Smith - Powder Technology, 2019 - Elsevier
The mechanisms of early granule growth are difficult to study and poorly understood.
Consolidation and layering play a critical role in the growth process. However, little is known …

Non-uniformity of binder distribution in high-shear granulation

GK Reynolds, CA Biggs, AD Salman, MJ Hounslow - Powder Technology, 2004 - Elsevier
Further experimental investigation based on a microscopic, or single granule, scale has

The kinetics of the granulation process: Right from the early stages

PK Le, P Avontuur, MJ Hounslow, AD Salman - Powder Technology, 2009 - Elsevier
In this study, experimentation and modelling were carried out to understand the granulation
process. This work assesses whether there is a significant difference in the aggregation rate …

High-shear granulation: An investigation into granule breakage rates

SAL de Koster, LX Liu, JD Litster, RM Smith - Advanced Powder …, 2021 - Elsevier
Granule breakage is an important rate process in wet granulation that promotes product
uniformity and controls product size and strength. In this work, a model to predict granule …

Evaluation of the effects of process parameters on granule mean size in a conical high shear granulator using response surface methodology

S Ranjbarian, F Farhadi - Powder technology, 2013 - Elsevier
Response surface methodology was used to investigate the effects of operating parameters
