(203c) Understanding Critical Parameters in Roller

2006-4-26 · There is an apparent need to develop roller compaction product process development and scale-up methodology that is based on fundamental understanding but is also applicable to actual practice. In this study, we examine the links between the consolidation mechanisms during roller compaction and the controllable parameters of a roller compactor.

Roller Compaction: Mechanistic understanding of ribbon

2020-7-20 · Roller compaction is a dry granulation technique in which the feed powder is subjected to different types of stresses, which are applied between two counter-rotating rollers. The stress applied during this process mediates both desired (intact ribbon) and undesired (ribbon splitting/sticking) bond formation. The phenomenon of ribbon splitting/sticking could originate
