Industrial Powder Mixing

What will I learn?
Powder flow and its significance in selecting the most appropriate mixers will be discussed. Quality assurance, powder sampling techniques, a practical discussion of the statistics of mixing and the value of statistics at the formulation stage will be covered. The handling, packaging and marketing of powder products will also be discussed.

This means that on completion of the course you’ll have an understanding of:

  • the relevance of powder flow to the mixing process
  • the concepts of free-flowing, cohesive, segregating, structured and coated powder systems
  • how to practically and theoretically assess the quality of a powder mixture
  • how to specify equipment fit for purpose.

How will I benefit?
Emphasis throughout is on the industrial application of basic principles. You’ll be given extensive interactive notes, and demonstrations, case studies and theory will be introduced wherever relevant.

The 2019 course programme and leaflet will be available approximately 3 months prior to the course. However, you can view and download the 2018 course details for further information by clicking the course leaflet and course programme link.

Day 1

  • Powder flow characteristics, free-flow, cohesion, segregation and structure
  • The selection of a mixer
