Implementation of an online thermal imaging to study the effect of process parameters of roller compactor
Peer-reviewed journal | 09 Jun 2023 | Contributor(s):: Omar, Chalak S., Hounslow, Michael J., Salman, Agba D.
During roller compaction, not only the properties of the primary powder affect the product quality but also the process parameters. Any change in the process parameters during roller compaction will result in changing the properties of the ribbon. In this study, the temperature of the ribbon...
