Experimental studies on distributions of granule size, binder content and porosity in batch drum granulation: Inferences on process modelling requirements and process sensitivities

Original language description

Batch granulation experiments on a lab-scale drum granulator for a Calcite/Polyvinyl alcohol in water (Calcite/PVOH-H2O) system are presented in this study. Experimental studies were carried out to study the aggregation kinetics and mechanism for this granulation recipe, whilst investigating the effects of binder-to-solids ratio and drum load on the granule size, binder content and porosity distributions. In particular, the effect of formulation properties and the granulation operating conditions on thebatch process dynamics and the end-granule properties are studied. The formulation properties considered include liquid surface tension, powder-liquid contact angle, dynamic yield stress, powder shape and liquid viscosity. The operating variables include the binder-to-solids ratio, binder addition duration and the binder addition mode. The sensitivity in the process and the non-homogeneity of key particle attributes (size, binder content, and porosity) is evident. The important process

Experimentální studie distribuce velikosti granulí, pojiva a porozity ve vsádkové granulaci: Důsledky pro modelování procesu a parametrickou citlivost

Czech description

Práce popisuje experimentální studii vlivu operačních parametrů na distribuci velikosti částic, pojiva a pórovitosti granulí vzniklých v kontinuální sudové granulaci. Je vyhodnocena parametrická citlivost a vyhodnoceny konstanty nutné pro následné matematické modelování.
