Roller compaction process development and scale up

2012-6-18 · The placebo model was then used to calculate scale up parameters from WP120 to WP200 roller compactor. While WP120 has a single screw speed, WP200 is equipped with a twin feed screw system. A limited nuer of roller compaction runs on WP200 was used as a calibration set to determine normal stress profile across ribbon width.

An evaluation of the Johanson model for roller

Roller compaction (RC) is a dry granulation technique applied to improve the flow and compressibility of drug formulations. RC implementation for high drug load formulations can be challenging due to flow issues and a high consumption of active pharmaceutical ingredient (API) for robust process development.

Pharmahub Resources: Roller Compactor: About

Abstract. The impact of material properties and process parameters are determined using a continuum model. Normal stresses for roller compaction are calculated from Johanson''s rolling theory. The boundary between the slip and nip regions is calculated using Johanson''s criterion, i.e. gradients of stress in slip and nip regions are assumed to be
