About the webinar

This lecture looks at pneumatic conveying from a rather different viewpoint. It aims to explain how particles flow and why pipelines block, why it is so easy to convey vertically up and why upward inclined pipelines should be avoided.

The fundamentals about dilute phase conveying and low velocity dense phase conveying are explained, together with everything you need to know about conveying air velocity to keep the material moving in any mode of flow, with the minimum power requirements. Bends (or is it elbows?) that are so convenient, yet so problematical, are dealt with in detail, as is the need for stepped pipelines for high pressure and high vacuum systems. A particular feature of the lecture is the highlighting of some of the problematic areas that exist in pneumatic conveying with pipeline layouts, material feeding and ‘difficult’ materials.
