The Art and Science of Industrial Mixing
See upcoming datesCourse Overview
You will learn what it takes to achieve good mixing and how to apply practical ideas to your processes. During the course, you will learn about:
- The fundamental relationships for impeller power, pumping capacity, blend time, shear rate, and flow patterns
- Different fluid mixing applications including liquid blending, solids suspension, powder addition, gas-liquid, and liquid-liquid dispersion
- How and when to use different types of impellers
- Relationships for determining, establishing, quantifying, and achieving process requirements
- The basics of mechanical design for mixers
- Typical components of mixing equipment, including tanks, motors, drives, seals, shafts, and impellers
Upon completion of this course you will be prepared to:
- Apply mixing fundamentals to your process applications
- Understand the importance of flow patterns
- Evaluate and quantify mixer performance for new or existing mixers using a Mixing Intensity Index
- Calculate mixer power and other operating characteristics
- Do geometrically similar scale-up calculations
- Identify ways to improve your mixing intensive processes
