CH032 - Flow of Solids in Bins, Hoppers, Chutes, and Feeders

From July 1, 2012 ASME are no longer running the AIChE courses.  For information on any AIChE courses please visit:  http://www.aiche.org/iltlanding.aspx
Should you have any questions please email  edu@aiche.org or telephone +1 800-242-4363 or +1 203-702-7660

This AIChE course provides participants with practical-based training for effective design and troubleshooting principles for handling bulk solids in bins, hoppers, feeders, and transfer chutes.  Strategies for alleviating costly flow problems are presented, as well as proven techniques to design storage, handling, and feeding equipment so that it operates efficiently, safely, and reliably from the start.

In this course, a review of bulk material flow fundamentals is presented, including common flow problems, types of flow patterns in equipment, and how flow properties of bulk solids are measured.  Feeder design and troubleshooting techniques are discussed, along with insight into unique flow problems that occur when handling fine powders.  The participant will also learn about common mechanisms of segregation and solutions to these costly problems, along with pragmatic advice for using flow aid devices.  The lectures are supplemented with real-life industrial case histories to illustrate the complex concepts taught.  Workshops are also provided to help increase participant understanding of the course theory and application. 

You will learn
- Pitfalls of poor bulk solids handling
- Common flow problems and their costly impacts
- Silo/bin/hopper flow patterns and their features
- Bulk solids flow properties testing and how their results are often used
- Bulk solids feeders and how to solve costly on-going problems
- Why fine powders can be flow rate restricted or flow uncontrollably
- How to design a bin or silo step-by-step
- Segregation mechanisms and how to implement practical solutions
- Common flow aids and how to select an appropriate device
- How to avoid plugging in transfer chutes and how to minimize wear and dusting

Instructors

Eric P. Maynard is the Director of Education and a Senior Consultant for Jenike & Johanson, Inc., a world-renowned engineering consulting firm specializing in the storage, flow and processing of powder and bulk solids. Mr. Maynard received his B.S. in Mechanical Engineering from Villanova University in Villanova, Pennsylvania and his M.S. in Mechanical Engineering from Worcester Polytechnic Institute in Worcester, Massachusetts. During his 16 years at Jenike & Johanson, he has designed handling systems for bulk solids including cement, coal, limestone, plastic powder, food products, and pharmaceuticals.
Mr. Maynard has gained valuable hands-on experience from working on over 500 solids handling and conveying projects, and currently specializes in the cement industry helping clients to reliably handle challenging bulk solids like clay, limestone, and fine/abrasive cement powder. He has specialized knowledge in the areas of dust explosions (NFPA membership), crushing technology, and static electricity generation. Mr. Maynard is the company’s primary lecturer on the storage, flow, and pneumatic conveying of bulk solids for the American Society of Mechanical Engineers (ASME) and American Institute of Chemical Engineers (AIChE), individual companies, in-house courses, and numerous conferences (e.g., Powder & Bulk Engineering, Powder & Bulk Solids, Pharmaceutical TechSource®).

Herman Purutyan is the Chief Executive Officer (CEO) of Jenike & Johanson. His organizational skills play a key role in the day-to-day operation of Jenike & Johanson, and his technical ability and wide experience in the field of storage and flow of solids have been recognized worldwide. Mr. Purutyan has 20 years of experience in designing reliable solids handling systems, and troubleshooting handling problems in industries as diverse as mining, power, chemicals, food and pharmaceuticals. He has designed silos, feeders and chutes for hard to handle materials such as coal, iron ore, bauxite, synthetic gypsum, titanium dioxide and chalk for clients around the world.
Mr. Purutyan has designed many degassing vessels for polymers such as polyethylene and polypropylene. His expertise includes designing and troubleshooting pneumatic conveying systems. He has been lecturing on solids handling for American Institute of Chemical Engineers (AIChE) and American Society of Mechanical Engineers (ASME) continued education programs for the past 18 years. He also lectures on pneumatic conveying, particle segregation, caking and attrition. Mr. Purutyan is a past team leader of ASME Structures for Bulk Solids Committee’s silo loadings sub-committee, charged with drafting the solids loadings calculation methodology. Herman received his Bachelors and Masters of Science degrees in Mechanical Engineering from Worcester Polytechnic Institute in Worcester, Massachusetts, and his MBA (Masters of Business Administration) from Babson College in Wellesley, Massachusetts. He has published dozens of articles on the filed of bulk solids handling and pneumatic conveying. He is the holder of two patents.

Thomas G. Troxel is a vice president at Jenike & Johanson and is a graduate of California Polytechnic State University in San Luis Obispo, California with a B.S. in Engineering Science. After graduating as the Outstanding Senior in the Engineering Science program in 1981, he worked at General Dynamics Co. prior to joining Jenike & Johanson. He helped to open the firm's San Luis Obispo, California facility in 1982, where he is currently a Vice President. Mr. Troxel has been intimately involved in many aspects of the firm's consulting and research activities on a wide range of projects including flow properties testing, modeling, blending, pneumatic conveying and fluidization.
Mr. Troxel has been a major force behind the firm's expansion of services in the areas of mechanical design engineering and supply of custom built equipment. The latter includes mass flow screw feeders, portable anti-segregation bins for pharmaceuticals, BINSERT®‚ tumble blenders, and storage bins for a wide variety of applications. His sound knowledge of basic engineering principles has added significantly to the firm's depth of talent and expertise available to solve problems in bulk solids flow. Mr. Troxel has published numerous articles and papers in the filed of bulk solid handling, and lectures on the subject both through professional organizations, such as AIChE and ASME, as well as to individual companies.
