Powder Flow: Particle Size-independent Variation of Bulk Excipients Tim Freeman
August 12, 2019
Microcrystalline Cellulose (MCC) has been used as a pharmaceutical excipient for many years, due to its abundance, ease of production and resistance to degradation.
Powder Flow: The Influence of Roller Compactor Process Parameters on Granule Properties Tim Freeman
July 17, 2019
Dry granulation by roller compaction is a continuous process applied routinely to convert fine, difficult to handle powders into uniform granular products that flow freely and perform efficiently in subsequent manufacturing steps.
Powder Flow: The Influence of Storage and Handling Tim Freeman
June 26, 2019
When working with powders, in-process performance and final product quality will be influenced by properties of the raw materials delivered to the process.
Powder Flow: The Influence of Particle Size and Shape on Flow Properties Tim Freeman
April 17, 2019
The size and shape of the particles within a powder are important factors in influencing behaviour, and many well-established techniques exist for measuring these properties.
Powder Flow: Batch Variability in spray coating Applications Tim Freeman
March 08, 2019
In spray coating applications, a fine powder, typically a polymer, is drawn from a storage device before being fluidised and ejected through a charged nozzle onto a substrate.
Powder Flow: Developing a Design Space for a Die Filling Operation Tim Freeman
February 19, 2019
