Powder Storage and Flow


Credit Hours:


The goal of this course is to describe introductory methods for designing bins, hoppers, and chutes for
storing and transferring particulate bulk solids. Persons successfully completing the course will be able
1. describe common indices used to assess powder flow,
2. apply the method of differential slices to estimate stresses in a bin or hopper,
3. design a hopper for continuous mass flow using the Jenike methodology,
4. calculate the mass flow rate from a hopper,
5. design chutes to ensure continuous flow, and describe common devices used to monitor material
levels and mass flow rates in hoppers,
6. describe how particle properties influence bulk powder flow properties
