When Powder Flows Like Water: Addressing Two-Phase Flow in Tablet Press Feed Systems

Paper Summary

In tabletting processes, production rate limitations can develop when feeding fine powders (median particle diameter less than 100 microns), regardless whether it’s a direct-compression blend or a granulation.  Similar rate limitations can develop when feeding into capsule filling equipment, granulators, or mills.  This article focuses on diagnosing and rectifying feed rate limitations in tablet presses.
