Pneumatic Impact
Lunch & Learn : Pneumatic Conveying Lecture Series
We are pleased to announce the complete, five-part pneumatic conveying lecture series by Jack Hilbert has been released in our Online Training Center.
In this five-part lecture series on pneumatic conveying, Jack Hilbert of Pneumatic Conveying Consultants, describes the applicability of pneumatic conveying to a multitude of uses and functionality within a plant. Examples of in-plant applications are given as well as an overview of the typical industries which rely on pneumatic conveying.
The basic pneumatic conveying system is described as well as types and modes of pneumatic conveying systems along with the advantages, disadvantages and application criteria for each one. Jack covers component section, troubleshooting and optimization of existing pneumatic conveying systems.
“Travel less – Learn more”
Information from this lecture can effectively help an engineer, formulator, or plant operator with the fundamentals pneumatic conveying required to help troubleshoot or select a new equipment for a pneumatic conveying application.
The lecture series includes downloadable class notes and a self administered quiz with answer sheet. The 21-day subscription allows you to watch and review each video class as many times as you need. All for only $158, payable via credit card online.

This is the first lecture in the five-part, Practical Overview of Pneumatic Conveying Series, we hope you enjoy it. Other lectures in the series will be available later this week and next week.
Fifteen years ago, we were asked by a steel plant in Mexico to develop a system for conveying large abrasive particles pneumatically. The one condition was that we should try to keep particle breakage to a minimum. The client also told us that the product was highly reactive with air, temperature ranging from 35°C to 900°C, and when conveyed hot, the heat loss should be kept at a minimum. Because particle sizes and conveying capacities were continuously being changed, we were asked to develop a general scale-up procedure that would cover a whole range of possibilities, while keeping operative cost to a minimum.
A word of caution, every material has its own personality and will react differently to temperature, pressure, friction and impact. Data cannot be directly extrapolated from experiments performed with other materials even if they have the same particle size distribution. This is critical to know when pneumatically conveying in low-velocity, dense phase mode.
At that time, there was little information or literature available regarding high temperature pneumatic conveying. The equipment available for high-temperature, dusty gas applications was extremely expensive. While we had some experience using hot valves with dirty gases, the maximum temperature the valves available was 300°C with a few exceptions some that went as high as 700°C. The expected life of this equipment was less than 6 months with a massive repairs required afterward.
