For dry granulation, an integrated systems model for a semi-continuous process was first proposed by Boukouvala et al. (2013).
What Is Dry Granulation?
Dry granulation serves as a lower-cost method of processing powder and powder blends. It does not require the use of a liquid binding agent, which eliminates the need for separate moisture addition and material drying stages.

Understanding The Dry Granulation Process
The original method of dry granulation employed a heavy duty tablet press to compact the dry powder. The compacting process in this case is known as slugging and the compacted material was therefore in the form of "slugs" - typically 25 mm in diameter and 10-15 mm thick. A hammer mill is ideal for breaking up the slugs to create granules.
