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.

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.

Sampling Plan for Combustible Dust Testing to Support a Dust Hazards Analysis
When: Tuesday, March 30, 2021, 2 p.m. Eastern/11 a.m. Pacific
Speaker: Dr. Ashok Ghose Dastidar, Vice President, Dust & Flammability Testing and Consulting Services, Fauske & Associates LLC
Dust Hazards Analysis (DHA) are required by the NFPA and many local fire codes for any industrial operation that handles or generates combustible dusts. The DHA is a systematic review of your process by a qualified person to assess the risks to your facility and plant personnel posed by combustible dust explosions and fires. For this type of analysis to be effective in minimizing the risk of a combustible dust hazard the combustion and explosion properties of the dust in question must be known. The test methods to ascertain these combustion and explosion properties are well known and have been presented here last year. The second key factor that should be addressed is “the dust in question.” Dust combustibility is not like gas/vapor combustibility; it is heavily dependent on particle size distribution and morphology. This presentation will discuss several factors that should be considered when General establishing a dust sampling plan for submitting material to a lab for analysis. Additionally, it will cover strategies that can be used to target testing specifically for credible accident scenarios.

To get your bulk material moving, flow aids can be helpful, or if misapplied, can be hurtful worsening your flow difficulties. This webinar will review common flow problems that occur in bins, silos, and hoppers, and what techniques can be used effectively to induce material flow. Sometimes gravity is not enough to get stubborn material to get moving, and this webinar can help you learn quickly about what works and just as importantly, what does not usually work!
During this webinar, we will discuss the following:
- Understand types of common flow problems with bulk solids
- Review a variety of flow aid devices
- Learn how to apply flow aids to alleviate flow problems
In his presentation, Dr. Cloney will review a number of case studies demonstrating how failures in prevention, protection, and isolation can lead to severe dust explosion disasters. When coupled with a failure to properly contain, collect, and clean combustible dust in facilities, these conditions can lead to catastrophic results.
In addition to demonstrating dust safety through case studies ranging from food products, wood, utilities, and additive manufacturing, Dr. Cloney will also review OSHA citations made through the general duty clause in 2018 to understand what materials, equipment, and conditions OSHA is focusing their regulatory efforts on and what areas you need to pay attention to in your facility.
When handling powders in bins, hoppers, and silos, we are most concerned with “what does it take to achieve reliable flow.” Although this is very important, not much attention is paid to the discharging device. The design of your feeding device is critical to maintaining reliable discharge from your bin or silo. If your feeder is not designed properly, flow from the bin or silo will effected.
The deadline for completing your company's Dust Hazards Analysis (DHA) is fast approaching. A DHA is required for all new facilities or facilities that have had major renovations before initial startup. However, older preexisting facilities are also included in this requirement to have a DHA performed. The original three-year deadline for having these DHAs completed was September 7, 2018. Recognizing the monumental task ahead for many companies, the NFPA committee decided to give an extension until 2020. Although the deadline is quickly approaching, many companies have not yet started their DHAs. Furthermore, global pandemic shut down many facilities or access to them just as DHAs were beginning.
