Design Example

Designing based on flow properties testing. Lecture 8, the final lecture in our main solids flow series.

About this Course

The basics of solids flow

Lecture 8 (the final section)

Joe Marinelli of Solids Handling Technologies takes you through a typical design example.  The example begins with an assignment you may receive to design a bin and feeder to reliably handle your product.

Joe discusses the actual data plots that would typically be generated during testing of your materials and their interpretation.  He uses the Jenike design approach to calculate opening sizes and hopper angles.


Joe discusses minimum opening size calculations and hopper angles for mass flow conical hoppers and wedge type hoppers.  He also describes funnel flow bin designs requiring calculation of your material’s rathole dimensions.  A design is ultimately created according to the data and calculations made during the presentation.

 The online video class is given along with handouts of the presentation and a quiz that will help to ensure your complete understanding of the concepts. Upon purchase of the course you will have 3 days to view the course before your access expires.
