Improve Particle Uniformity with Roller Mill Technology ...

Roller mill technology has advantages over other grinding methods. For example, hammer mills grind using impact at high speeds, relying on a perforated sizing screen to control particle size. In contrast, roller mills typically create 50 to 75% fewer fines and improve particle uniformity by 50 to 100%.

Roller compaction: new trends, challenges and solutions

Oct 15, 2020 · The flow, density and uniformity of the precompaction blend all impact the target properties of the final dosage form and should be closely monitored during development. A filler/diluent and binder are typically included in the preroller compaction blend because, if included at the extragranulation phase, segregation could occur.
