Roller compaction is a method of powder compaction of dry powders into a solid mass known as the ribbon. This process is achieved by feeding powder through a set of directly opposed, counter-rotating rollers. The process avoids the use of liquids …

The compaction was made at room temperature (25 °C, 45 ± 2% RH) at 5 mm/min of speed (quasi-static). For each pressure level, the mean of three replicates was calculated. Different milling parameters result in different particle size distributions and wide ranges of granule size can exhibit different compaction properties.

Roller compaction technology for dry granulation is a process of transforming the powder into suitable granules with predictable density, size and shape. The roller compaction granulation involves the action of rotating rollers, milling and material grading …
