Abstract

Experiments have been carried out to study the effect of agitation on particle size distribution of aspirin powder and aspirin agglomerates during vacuum contact agitated drying. Morphology G3 by Malvern was used to find the size distribution of the materials under investigation before and after the drying process at 0.1, 0.5 and 0.9 µm.  It was found that due to agitation, aspirin powder portrayed from negligible to significant agglomeration dependent on the diameter of the material under investigation. While attrition and agglomeration compete together during the drying process of aspirin agglomerates, with attrition dominating at 0.1 and 0.5µm and agglomeration at 0.9 µm.
