Overview
Agitators and mixers have been around for centuries. They are still an essential part of processes in countless industries from manufacturing paint to treating water. As technology has progressed, so have mixing apparatus. Mixers, agitators and blenders continue to evolve as new requirements and new applications are identified and as technology increases. For example, not too long ago, energy costs were low. Thus, energy consumption of an agitator was not usually a major design consideration. Nowadays, however, energy costs are high enough to warrant consideration when designing or selecting a mixer for your application.
The course author, who has over 40 years of experience designing agitators and mixers for process applications, provides a wealth of information and "been there, done that" experience.
This course is provided in two forms for your convenience. The course may be studied as a “podcast” or audio presentation.
