The Art and Science of Industrial Mixing

October 21 - 23, 2025

$2195 per person.

Team discount: $1995 per person

Live in Chicago, IL

21 hours


This course covers the essentials of liquid mixing, both the equipment and the process. Parameters that influence mixing will be discussed to allow the participant to evaluate their existing mixing processes for optimization and improvement. Flow visualization in a transparent mixing vessel will demonstrate best practices and enhance course lectures. Class exercises using the Mixing Index will show its value in process evaluation and scale-up. In addition to the essentials, this class will also examine geometric and non-geometric scale-up. This course is intended for both new and experienced personnel.



During this course, you will:

  • Learn what it takes to achieve good mixing and how to apply practical ideas to solve process problems
  • Examine the relationships between impeller power, pumping capacity, the Mixing Index, and blend time
  • Analyze different fluid mixing applications, such as liquid blending, solids suspension, powder addition, gas-liquid dispersion, and liquid-liquid mixing
  • Gain an understanding of the different types of impellers and when to use them
  • Calculate mixer power and examine different options for scaling up and down the entire mixing process
  • Identify ways to troubleshoot and improve your mixing intensive processes
