Influence of interface energy of primary particles on the deformation and breakage behaviour of agglomerates sheared in a powder bed

Identifying the process conditions leading to desired granule properties in terms of size, shape and strength during high shear granulation process is very challenging and has been widely based on trial and errors. The reported work, as part of a project sponsored by a consortium (EPSRC, Hosokawa, Borax, P&G, Pfizer), provides an in-depth explanation elaborating reasons for the formation of granules with specific shape and structure. The methodology is based on mathematical modelling techniques and can reduce extensive trial and error, minimising the process development time. The research enabled the relevant industries to optimise process conditions for controlled granule structures.
