Pneumatic transport systems are commonly designed as though they carry a liquid, which is usually incompressible. Often, little thought is given to the addition of number and type of elbows, as well as mode of transport, namely dilute or dense phase. Terminology used for design of systems is generally not taught in academia, thus, personnel trying to troubleshoot a conveying system may not be aware of conveying modes, required velocities, and level of solids loading. As a result, conveying problems such as plugging/buildup, rate restrictions, fines generation, and rapid abrasive wear of pipelines can result. These problems can be difficult to troubleshoot if personnel are not properly training in the science of pneumatic conveying, and this leads to a costly trial-and-error approach to problems solving.
Topics covered include:

  • Learn about causes of wear and attrition
  • Review effective techniques to control velocity increases
  • Discuss solution approaches to costly problems
