Exploring the impact of particle shape on bulk powder properties

Wednesday 14 August 2019

In a series of articles on LinkedIn, Tim Freeman, Managing Director of Freeman Technology, draws on over 20 years of experience in the industry and provides some valuable insights into powder flowability.

In his latest post, ‘Exploring the Impact of Particle Shape on Bulk Powder Properties’, he explores the many variables that influence powder behaviour. Following on from ‘Exploring the Impact of Particle Size' he looks at the importance of another critical particle parameter - shape. Many powder processors recognise that particle shape influences powder behaviour, perhaps most significantly flowability, but until relatively recently it has been difficult to access any form of quantitative correlation. Modern advances in shape measurement, as well as those in powder characterisation, have transformed our ability to develop robust relationships between these properties and understanding in this area is now advancing rapidly.

This article looks at:

  • The mechanisms of powder flow
  • Investigating correlations between particle shape and flow energy
  • The practical relevance of shape
