The basics of solids flow

Lecture 2

This lecture will further develop the topics of flow problems, their effects, and flow patterns discussed during the previous course, "Flow Problems, Their Effects, and Flow Patterns." The design principles required to ensure reliable flow from your bins, hoppers, and feeders will be covered extensively.

Topics covered in this lecture include the ASTM standard for measuring bulk solids flow properties, using the Jenike Shear Tester.  This device allows the user to determine material wall friction properties as well as its cohesive strength.  Wall friction tests yielding the angle of wall friction, leads to determination of hopper angles required to ensure flow along the walls, which is mass flow.

Additionally, measurement of a bulk solid’s cohesive strength is illustrated.  Once your material’s cohesive strength is determined, you will learn how to calculate hopper opening sizes required to prevent arching.

 This one hour video online 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.
