Storage and flow of bulk solids/particulate materials seems relatively simple at first glance – in many cases, it is just simply a wide spot in the line. However, experience suggests that many vexing process problems and headaches are caused by numerous issues associated with bins and hoppers, such as arching, rathole formation, incomplete emptying, and segregation.

This webinar addresses the fundamentals of the flow and storage of bulk solids, and clearly demonstrates the considerable science behind the design and use of storage vessels for solids. In particular, the various profiles that develop in silos are examined along with the advantages and disadvantages for each. A key to understanding the flow of solids is how stresses develop in silos both with the solids at rest and when the solids are emptied from the silo. Flow property testing of bulk solids is discussed, and how the data is used to determine key parameters for a silo design. Numerous practical examples are used throughout the webinar to illustrate the fundamental concepts.

This is the second in a series on Solids Processing and Particle Technology. Please note that each webinar in the series requires separate registration, and has been designed to function as both a standalone presentation and a component in the series.
