New paper! Head to the papers page to read the article published by Invite GmbH & the University of Düsseldorf.

The study points out the importance of material hardness & how it can be predicted thanks to the process parameters of roll compaction :

  • Specific compaction force
  • Roll speed
  • Gap width

For the 1st time, 2 depending process parameters were used to predict granule failure load :

  • Torque of the granulation unit
  • Throughput of the material

The hardness of the granule was controlled in-line when the specific compaction force was increased during compaction. This process introduces in-line control of material hardness.
