Dry Roller Compaction Vs. Wet Granulation Processes

While dry roller compaction is not suitable for all agglomeration requirements, it does offer many superior characteristics and cost-advantages when compared to wet granulation processes. Dry roller compaction:

  • Eliminates the need for liquid binders and drying equipment associated with wet granulation. Micro problems are nearly non-existent.
  • Offers the economy of continuous operation and greater throughput. Wet granulation often requires batch processing with stop-and-go operating cycles.
  • Produces the more precise granule size and bulk density preferred as an intermediate material in tableting or a final, flowable powder product.
