Experimental investigation of granule size and shape dynamics in twin-screw granulation.
A twin-screw granulator (TSG), a promising equipment for continuous high shear wet granulation (HSWG), achieves the desired level of mixing by a combination of the appropriate screw configuration and a suitable set of process settings (e.g. feed rate, screw speed, etc.), thus producing a certain granule size and shape distribution (GSSD). However, the primary sizing and shaping mechanism behind...
متن کاملTwin-Screw Extruder and Effective Parameters on the HDPE Extrusion Process
In the process of polyethylene extrusion polymer material similar to powder or granule is under compression, melting and transmission operation and on base of special form, extrudate has been produced. Twin-screw extruders are applicable in industries because of their high capacity. The powder mixing with chemical additives and melting with thermal and mechanical energy in three zones (feed, co...
متن کاملEffect of Conveying and Distributive Mixing Elements on Breakage Phenomenon in Twin Screw Granulation
Twin screw wet granulation (TSG) is gaining more attention and becoming an important process in the pharmaceutical industry. The process is widely implemented because of its flexibility, short residence time, and small equipment footprint. Past studies have shown that screw elements can have a significant impact on the performance of the TSG process. In addition, these studies identified that b...
متن کاملFormulation and Comparison of Alternative Multiscale Models for Drum Granulation
Continuous granulation of powders is a unit operation that poses both operational and modelling challenges. We discuss the formulation of several alternative multiscale models for a drum granulator. All combine a vessel scale population balance model with a granule scale discrete element method (DEM) model, but they are linked using different multiscale integration frameworks. The inter-scale f...

A two-dimensional balance model of populations distributed by property was developed using the ordinates of particle diameter andparticle density. This model makes it possible to calculate the spectrums of granulation changing over time in the fluidized bed duringbatch operation and in addition to calculate the time-dependent size distribution of the product granulate for continuous...
