Course Description
The course presents the principles and techniques of mixing free-flowing or cohesive powders. Selection of suitable industrial equipment for particular mixing duties will be discussed analyzing mixer performance in terms of process advantages, mixture quality and the flexibility of the mixer for multi-product manufacture.

Other topics to be covered include powder sampling techniques, a practical discussion of the statistics of mixing, the significance of statistics in powder formulation, the aggregation of mixtures, and the use of lubricants and flow aids for powders.

There will be special emphasis on the mixing of cohesive powders and the opportunities this can present to produce superior quality mixtures. The handling, packaging and marketing of powder products will also be discussed. Throughout the course, the faculty will relate principles to specific industrial problems.
