W1. Powder Flow I: Measuring Powder Flowability & Its
 Applications: A Hands-On Design-Oriented Workshop
Nashville, TN • January 19-20, 2009• Registration form•Syllabus
An intense 2-day powder flow & handling workshop, for those involved in solids processing issues in which flow properties are critical, including material handling, feeding operations, roll pressing and tabletting. This course lays the groundwork for understanding the unique nature of powder flow properties, and its impact on processing & compaction, through team design problems and first hand lab measurements. Highlights include:

• Team design problems in hopper arching/ratholing, mass feed rate, stress transmission in tabletting & roll press nip pressure.
• Measurement of powder flowability, powder friction, wall friction by automated shear cell; aerated powder cohesion, permeability, and deaeration time by fluid-bed testing
• Particle sizing by imaging and laser diffraction (Canty/Sympatec Inc.)
• Understanding the impact of powder properties on hopper discharge, mass feed rates, and solids handling, and the impact of friction and permeability on tabletting and roll pressing, or similar filling or compaction processes
• Hopper discharge rate, stress and segregation experiments
• Mini-roller compactor (Vector Corp.) & tablet die stress demonstrations.
