Preventing Segregation and Creating Optimal Blending in Bulk Handling Process Equipment

When: Tuesday, August 16, 2022 at 2 p.m. Eastern/11 a.m. Pacific
Speaker: Dr. Kerry Johanson, chief operations officer, Material Flow Solutions Inc.

One of the significant contributors to production downtime and quality issues is segregation (or separation) of material blends during processing. Therefore, it is critical to understand and control segregation in process equipment. This webinar will address this issue using a systematic approach using sound scientific principals as a guide.

Segregation prevention based on in-process blending requires knowledge of several things. First, an understanding of how easily measured flow properties can/will influence the velocity and velocity profiles in process equipment. Second, an understanding of how to measure the segregation pattern and magnitude for the material placed in a given process. Finally, an understanding of how combining information about velocities and velocity profiles with segregation patterns can enhance (or mitigate) segregation present in the system. To fix a segregation problem, information regarding the velocity of material in the process equipment must be matched with the expected segregation profile or pattern. Some velocity profiles increase segregation, and some velocity profiles decrease segregation as material leaves handling systems. The trick is to know what velocity profile will help with a material’s unique segregation behavior.

Strategies for Improving Dryer Performance

When: Tuesday, June 7, 2022 at 2 p.m. Eastern/11 a.m. Pacific
Speaker: Karl Jacob, lecturer for chemical engineering at the University of Michigan

Despite the best design intentions of dryer engineers, many dryers do not operate at top performance, falling short of moisture specification, desired product rate, or experiencing product performance issues. During this webinar, we will examine some of the more common causes for lack of dryer performance and how to remedy these issues. Some of the more common problems are air maldistribution in convection dryers, formation of solid rinds in contact dryers, balling of products, and equilibrium moisture considerations.  In each case, we will present strategies that can be practically implemented to improve dryer performance.

Attend this webinar to learn:

  • The most common issues which affect dryer performance for both convective and conduction dryers.
  • How one can design for good air distribution in a dryer.
  • The causes for slow drying with vacuum batch contact dryers and potential solutions to improve performance.

Hood Design Optimization for Effective Dust Control
When: Tuesday, January 25, 2022, 2 p.m. Eastern/11 a.m. Pacific
Speaker: Diane Cave P.Eng, regional manager of Eastern Canada, Element6 Solutions

In many dust collection applications there is often little thought given to the final collection point: the hood. Hoods can be the most important part of the system; if the hood is located poorly or designed inadequately, then the system will not collect the dust effectively. 

The objective of this webinar is to provide an overview of the following:

  • Why hoods are important
  • How hoods affect the system collection
  • Hood locations
  • Basic design of common hoods

Cave has spent the past 16 years working with the design, installation, and retrofitting of dust collection systems in industries ranging from sawmills and grain installations to food and beverage and specialty chemicals. Her expertise covers all aspects of dust collection systems from troubleshooting system issues to upgrading systems to meet current codes and standards. Cave has also assessed hundreds of dust collection systems for combustible dust hazards using the latest NFPA codes and standards. She can also provide advice and design experience for explosion protection systems, vessel retrofits, Pred verification, and static bonding and grounding. Cave has a degree in Chemical Engineering from Dalhousie University in Halifax, Nova Scotia.

Optimizing Existing Pneumatic Conveying Systems 
When: Tuesday, November 9, 2021, 2 p.m. Eastern/11 a.m. Pacific
Speaker: Jack D. Hilbert, consultant, Pneumatic Conveying Consultants LLC

Pneumatic conveying systems are found in a wide cross section of industries and applications and have been a proven means of moving dry bulk solids. As companies change their business model and product wheels to meet market demands, existing pneumatic conveying systems often need to be repurposed to meet those new needs. Changes can be necessary with respect to material properties, rates, distances, functionality, etc. There are several techniques that can be implemented to “optimize” the performance of existing pneumatic conveying systems to meet those new needs. 

This webinar will present several of those techniques and how they can be implemented into an existing system, as well as how implementing them into new system designs can give “future capabilities” to a new system without incurring major retrofit costs later on. Production planners, facility engineers, operations personnel, etc., will all benefit from the information to be presented.

Hilbert spent nearly 40 years as a registered professional engineer in several states. After working for more than 32 years for globally based companies providing pneumatic conveying systems and equipment, he joined forces with Paul Solt in the pneumatic conveying consulting business, Pneumatic Conveying Consultants LLC, located in the Schnecksville, PA.

The Science of Metal Dust Explosions: How Big Is the Problem and Why Are They so Severe? 
When: Tuesday, October 5, 2021, 12 p.m. Eastern/9 a.m. Pacific
Speaker: Dr. Chris Cloney, PEng, managing director and lead researcher at DustEx Research

Only 10-20% of dust explosion incidents reported internationally involved metal dusts. However, these incidents report a disproportionately higher number of fatalities than with organic materials. Why is this?

This presentation will explore the science behind metal dust explosions, including international loss history, equipment and materials involved, and what properties make metal dust explosions so severe.

Practical considerations will also be reviewed, including minimum ignition energy, challenges with dust collection and isolation, response to fires, and safe use of inerting systems.

Cloney is managing director and lead researcher at DustEx Research, a company with a worldwide focus on increasing awareness of combustible dust hazards and reducing personal and financial loss from fire and explosion incidents. Cloney is a recognized expert in the field of combustible dust research publishing over 15 peer-reviewed journal articles and presenting at conferences in the US, Canada, China, Norway, the UK, Poland, and Germany.

How to Select the Right Feeder for Your Application
When: Tuesday, September 21, 2021, 2 p.m. Eastern/11 a.m. Pacific
Speaker: Joseph Marinelli, president, Solids Handling Technologies Inc.

In this webinar, Marinelli will examine a flow chart approach to proper feeder selection. Improper design of volumetric and gravimetric bulk solids feeders can lead to flow problems, process upsets, and downtime. In most cases, the feeder design is as important as the bin or silo design. However, the feeder is often ignored resulting in serious consequences.

The flow chart will walk you through a logical approach to determining the type feeder you should use for your application. Attend this webinar and learn:

• The importance of the feeder in relation to the bin to which it is attached
• Design techniques for volumetric feeders such as screws, belts, rotary valves, and specialty feeders
• Benefits of gravimetric feeders such as weigh belts, loss-in-weight, and gain-in-weight feeders

Marinelli 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.
