BULK SOLIDS FLOW in Storage & Handling

Want to learn the basics of bulk material handling? Interested in brushing up on what you already know? Jenike & Johanson Ltd, is pleased to offer a 2-day course in bulk solids handling:

Dates: December 11-12, 2018
Location: Mississauga, Ontario
Venue: Jenike & Johanson Ltd., 3397 American Drive Unit 10
Instructors: Eric Maynard / Tracy Holmes

Presented by Eric Maynard, Vice President & Director of Education for Jenike & Johanson Inc,  this course will give you a strong fundamental understanding of bulk solids and their behavior, along with the general principles and practical applications of solids flow. You’ll find out how and why typical flow problems occur, and what simple, practical steps you can take to solve them. You’ll learn how to design bulk material-handling systems that work the way you want. Conquer your company’s flow difficulties by attending!


  • Cover a wide range of equipment types and the solutions to flow problems commonly associated with each of them.
  • Gain a better understanding of how friction, cohesion, compressibility, and other properties affect the flow of solids through various types of feeders, chutes, reactors, bins and hoppers.
  • See how to specify and select hardware best suited to various bulk solid flow problems and objectives, including how to retrofit existing equipment to correct flow problems.
  • Solve problems associated with solids handling, such as lost production, downtime, extra labour, poor quality control, spoiled material, and unreliable equipment.
  • See field-scale mass flow and funnel flow patterns along with various other practical demonstrations with physical models.
  • Be alerted to the pitfalls in handling bulk solids.


Attendees will learn critical design methodology for dealing with bulk solids emergencies or planning for new installations or plant expansions that incorporate solids handling:

  • Typical flow problems and flow patterns
  • Flow properties of bulk solids
  • Volumetric and gravimetric feeders
  • Calculating solids discharge rates
  • Chute design
  • Stockpile design
  • Fine powder handling
  • Particle segregation
  • Silo Failures
  • Flow corrective devices


Design, project, and research engineers, as well as plant operation personnel responsible for solving and preventing flow problems or purchasing solids handling equipment, will benefit from the valuable information provided in this course.

Jenike & Johanson engineers have been presenting courses for over 30 years. The courses have also been upgraded significantly in the past three years.


Register today and put an end to your time-wasting and money-losing flow problems. To register, contact Tracy Holmes at Jenike & Johanson. Tracy can be reached at 905-694-9769, ext. 229 or by email to tracyh@jenike.com.

Course fee for the two-day session is $1,800 CAD, which includes lunch both days. (Discounts available for multiple attendees from the same office.)

If you are interested in this course, but are unable to attend, please let us know. We can schedule another open course, or we can provide a custom course at your facility to suit your company’s particular flow-related concerns.

This course will be held at the Jenike & Johanson Office in Mississauga, Ontario.


Jenike & Johanson is a consulting engineering firm specializing in the science and technology of bulk solids handling. In our six laboratories in the United States, Canada, Chile, Australia, and Brazil we have tested more than 13,000 bulk solids and used the results to design accurate, cost-effective solutions to flow-related problems for more than 3,000 companies around the world in such industries as chemicals, pharmaceuticals, energy, mining, consumer goods, solid waste and more.

Eric joined Jenike & Johanson in 1996. He has published over 50 articles on the storage, flow, and pneumatic transport of bulk solids. He is the principal instructor for the “Flow of solids in bins, hoppers, chutes, and feeders” and “Pneumatic conveying of bulk solids” courses sponsored four times per year by the American Institute of Chemical Engineers (AIChE) Continuing Education Program. Eric has presented bulk material and pneumatic conveying technology at over 300 training events world-wide. He has designed more than 750 bulk material handling and conveying systems for various powders and bulk solids, with a special focus on the cement, power, and mining industries. Mr. Maynard is responsible for internal training of engineers at Jenike & Johanson. Eric has particular interest in crushing technologies for minerals, as well as in the safety aspects of dust explosions and powder electrostatics. He has received certified training on dust hazards analysis (DHA; per NFPA 652 chapter 7 requirements) and can perform inspections on the unique hazards with combustible dusts such as foods, plastics, metal powders, and agricultural materials/wood. He is a member of ASME, AIChE, and the National Fire Protection Association (NFPA). Eric received his Bachelor’s degree in Mechanical Engineering from Villanova University and a Master’s degree in Mechanical Engineering from Worcester Polytechnic Institute.

Tracy Holmes is President of Jenike & Johanson Ltd. in Canada, and a senior project engineer. She received her B.ASc. in Civil Engineering from the University of Waterloo in Ontario. She specializes in the design and evaluation of bulk solids handling systems. Since joining JJL in 1994, Tracy has provided consulting services to a broad spectrum of national and international clients, troubleshooting and recommending corrective actions for flow problems, providing recommendations to avoid solid flow related problems in new installations.

In addition, she has hands-on experience and knowledge of measuring the flow properties of bulk solids. She frequently lectures at J&J and directly for clients, as well as through organizations such as Powder & Bulk Solids, and American Institiute of Chemical Engineers, (AIChE).

She has authored and presented technical papers on subjects including reliable bulk solids handling, effective bin and feeder design, shipping of fine moist cargoes, and silo structural failures and maintenance. Her papers have been published in periodicals including CIM Journal, Powder & Bulk Engineering, and World Coal and she has lectured at mining conferences such as Canadian Mineral Processors (CMP), Society for Mining, Metallurgy, and Exploration Inc. (SME), and the International Mineral Processing Congress (IMPC).
