Abstract

The invention relates to a continuous dry granulation method and non-invasive monitoring and control of the dry granulation method. The invention further describes a dry granulation system and uses thereof. In particular, the non-invasive monitoring methods employ a sound, force, strain, vibration and/or acceleration sensor in order to determine the mechanical strength of a compacted material during a dry granulation process. Further, the compaction parameters of the compacting unit of the granulation process may be controlled to maintain a target mechanical strength of the compacted material.
