Live online course – starts on Tuesday 8 June 2021.

As chemical engineers, our primary purpose is to add value to materials through the judicious selection and then optimisation of the building blocks of our profession-unit operations. However for unit operations featuring bulk solids value, our efforts can be undermined if the flow is not controlled. Unlike the flow of liquids, the flow of bulk solids is complex and not well covered in undergraduate courses.

This intense online course has therefore been tailored specifically for chemical engineers and addresses this Blind Spot by providing a fundamental understanding of the science underpinning bulk solids flow behaviour together with simple, practical steps that can be taken to solve but ideally avoid common problems.

Learning outcomes

Participants will learn how and why typical bulk material flow problems occur by:

  • covering a wide range of equipment types and the solutions to flow problems commonly associated with each of them
  • gaining a better understanding of how wall friction, cohesive strength, compressibility, permeability, and other properties affect the flow of solids through various types of feeders, blenders, chutes, bins, and hoppers
  • seeing how to specify and select hardware best suited to various bulk solid flow problems and objectives; including how to retrofit equipment to correct flow problems
  • identifying and solving flow problems involving lost production, plant downtime, extra labour, poor quality control, wasted material, and unreliable equipment.

Who will benefit?

Chemical Engineers and allied professionals involved in the study (including safety and environmental aspects), detailed design, and commissioning of value chains or procurement of equipment to handle bulk solids as well as anyone responsible for solving and preventing flow problems.

Course outline

  • Flow (liquid vs bulk solid systems)
  • Typical bulk solids flow problems/patterns
  • Flow properties characterisation,
  • Hopper flow patterns (funnel and mass flow)
  • Mixing/blending theory and types of mixers
  • Segregation of powders and bulk solids

The material is customised for on-line delivery and the course will still be interactive. Delegates will be able to raise questions, make comments and interact with the presenters in real-time.

Since joining Jenike & Johanson in 1996, Maynard has published over 50 articles on the storage, flow, and pneumatic transport of bulk solids. In addition to being responsible for internal training of new engineers at Jenike & Johanson, Maynard 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. He has also presented bulk material and pneumatic conveying technology at over 300 training events world-wide and 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.

Eric is a special expert on NFPA committees 654, 91, and 655 and an active member of the 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.

Jenike & Johanson

Corin is the Operations Manager for Jenike & Johanson in Perth, Australia, and is passionate about applying the science of bulk solids handling to help people and organisations succeed, especially those in the resources sector.

The flow behaviour of bulk solids is deceptively complex and often treated with contempt during the design stage hence there are plenty of “opportunities for improvement”, in almost every industry. As a bulk solids handling engineer with 15 years’ experience, Corin therefore gets plenty of opportunity to indulge his passion, which he enjoys sharing with others. This deep practical experience combined with his accomplished and entertaining presentation style ensures that you won’t be disappointed!
