QbD Solid Fraction Analysis In Roller Compaction Operations

Roller compaction is a continuous dry granulation process used to increase the bulk density and uniformity of powders into free flowing granules used in downstream manufacturing operations. It is a complex procedure due to the diversity of available powder blends and the control and adjustment parameters involved in the process. The character and homogeneity of the produced ribbon is controlled by a number of factors, such as the properties of the individual powders themselves, roll speed, roll gap/nip angle, and feed speed; all of which subsequently determine the character of the granules produced (size distribution, density and flow behavior).
