What will I learn?

This short course will outline the principles and methods for characterising the chemical, physical and mechanical properties of powders at length scales ranging from molecular to single particle and bulk levels. Sample preparation and the state-of-the-art techniques for particle characterisation will be detailed.

How will I benefit?

The course is delivered by over 10 presenters with internationally-leading expertise in their own speciality fields. The outcome of the course should enable you to choose what and how to characterise the powder and suspension properties, and to diagnose particular process and product issues of interest.

Course aims

Success in the handling and processing of particulate materials is based on science. It is important for companies using and producing particulates to have in-house expertise in this science.
This course aims to provide participants with a broad understanding of the fundamentals of particle technology with emphasis on basic concepts and practical problems.

Course presenters

The course will be delivered by specialist presenters who are all actively engaged in areas of particle technology and who are familiar with the needs of the industry.

  • Richard Farnish, Principal Research Fellow, Consulting Engineer, Wolfson Centre, University of Greenwich
  • Mojtaba Ghadiri, Professor of Chemical Engineering, University of Leeds
  • Martin Rhodes, Emeritus Professor, Monash University, and Visiting Professor University of Leeds
  • Rachel Smith, Senior Lecturer, University of Sheffield

Course overview

Participants will appreciate the practical way in which particle technology principles are put across in a relaxed atmosphere. The programme, though intensive, will provide time for participants and presenters to meet and interact.

Challenges of powder handling and processing – setting the scene

Why are difficulties in the handling powders overlooked at the design stage? Why are powder-related problems the cause of so many production stoppages? What industries are involved. The current state of knowledge. What are the challenges?

Characterisation of particles and powders and sampling of powders

Sampling methods to ensure representative samples. Defining an appropriate particle size. Particle size distributions. Choosing the correct mean particle size. Size measurement techniques: how they work, the most appropriate for each application.

Mixing and segregation of powders

Types of mixture. How does particle size segregation occur? Why is segregation such a problem? Minimising segregation and achieving good mixing. Assessing mixture quality, mixer performance.
