When I became an adjunct professor at the University of Rhode Island, I realized that most books on the subject of bulk solids testing and hopper design were either very terse or rather intense for readers who did not have a mechanical engineering background. My students encouraged me to convert my course material into a text book. Yes, some of the text may have been taken from my prior publications, but I figure that it isn’t plagiarism when you copy your own material. I only disclose design methods that are available in the open literature.
A few of the formulas I derived on my own, but they were all based on fundamental engineering principles. Consequently, some of the analyses that I present may be slightly different than what you might find published elsewhere, but I use them when I consult.
The paperback is 175 pages long, and includes sections on analysis of stress, stresses in hoppers, flow property testing, bin design, feeders and flow aids, chute design, and design of process vessels.
The publisher charged me $8.00 per book, but the catch was I had to purchase one hundred of them! So I'm offering them on my website for $20.00, which includes USPS media rate shipping, with the hope that I will sell enough to be able to provide them for free to my students. I figure that if I'm charitable, I won't get into too much trouble for helping myself to some images from the web without permission.
I recently published a second edition with additional material and additional typos. You can purchase it by using Paypal, or send an email to email@example.com and we can figure out another arrangement. If you are outside the U.S., contact me, and I can send you a pdf version.
Thank you for your business!
Contact me if you'd like a copy of the Excel workbook that I use to analyze powder test results and design bins, silos, and hoppers.
