Roller compaction uses an auger-feed system that delivers powder uniformly between two pressure rollers. The powder is compacted into a ribbon between these rollers prior to milling through a low-shear mill. Uniform density across the ribbon is critical to achieving granules with a uniform particle size distribution.

In the dry granulation line, the roller compactor serves as a granulation method. In this unit, the powders are fed into a hopper and then conveyed by the feed screw to two counter rotating rolls. The powder is gripped by the rolls and pulled into the nip area of the compacting rolls before being compacted into a ribbon.
