An introduction to solids flow. Lecture 1 in our main solids flow series.
During this lecture, Joe Marinelli of Solids Handling Technologies will guide you through several common bulk solids flow issues with solutions based on Dr. Andrew Jenike’s renowned work, “Storage and Flow of Solids, Bulletin No. 123”.
Topics covered in this lecture include flow problems due to arching and ratholing, flooding issues, limiting discharge rates and segregation problems. These issues can have devastating results such as limiting live storage, caking and spoilage, and even potential structural problems with your silo.
Solutions to the above problems are dependent on the flow pattern that develops in your silo or storage vessel. Joe discusses poor flow such as exhibited by “funnel flow” where significant product can remain stagnant and reliable flow using “mass flow” where all the product moves upon discharge. As well, a combination flow pattern called “expanded flow” is discussed.
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.
Joseph Marinelli, President of Solids Handling Technologies, Inc. in Fort Mill, SC is a bulk materials handling expert who has taught hundreds of highly acclaimed engineering seminars. Since 1972, he has been active in testing bulk solids and consulting on materials handling systems design. With Jenike & Johanson, Inc., world-renowned experts on solids handling, Mr. Marinelli received his Bachelor of Science degree in Mechanical Engineering, from Northeastern University in Boston, MA.
Mr. Marinelli has also worked for manufacturers of solids handling equipment, such as feeders and silos. This background provides a unique blend of consulting and manufacturing experience to solve solids flow problems.
He lectures frequently, teaching courses on solids flow principles and flow property testing, and has authored several papers and an encyclopedia section on the subject. Since 1997, he has been involved with very popular seminars at the University of Wisconsin in the areas of bin and feeder design and solids flow property testing. He is also a columnist (“Powder Perspectives”) for the website, www.powderbulksolids.com
