Yes, the flow of MCC pellets (Cellets) through a Wurster fluid-bed coater shows better performance as the Cellets’ particle size increases. The flow behavior is outperforming standard MCC powder. This was investigated by Mohylyuk et al. (2019), doi: 10.1016/j.jddst.2019.101320. Find more information: Is there an impact of the particle size on powder behavior in a Wurster fluid-bed process?
