Free Webinar on Air and Particle Flow in Pipelines Offered

Pneumatic conveying consultant Dr. David Mills, will present “Air and Particle Flow in Pipelines”, as part of Powder & Bulk Solids’ DryPro webinar series, on June 18.
 
This webinar will look 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 will be 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.

Mills is a 1961 graduate of Woolwich Polytechnic in London, with a first class honours degree in Mechanical Engineering. He first worked in industry as a nuclear engineer with Atomic Power Constructions Ltd, and then in academia as a thermodynamicist at TEMS Polytechnic, specializing in heat and mass transfer. He undertook a PhD program on Pneumatic Conveying in 1973, and has been working in this area ever since, first at the University of Grenitch in London, then as Professor of Bulk Solids Handling at Glasgow Caledonian University in Scotland.

Since 1997, Mills has been operating as an independent consultant. He has written more than 200 articles for technical journals and conferences and has presented short courses and undertaken consultancy on a worldwide basis. In 2003, he was appointed Conjoint Professor at the University of Newcastle in Australia, and in 2007, he received the UK Institution of Mechanical Engineers Solids Handling Award in recognition of his professional excellence in bulk solids handling technology. In 2010, he was appointed Adjunct Professor at the University of the Witwatersrand in Johannesburg. He is author of the ‘Pneumatic Conveying Design Guide’ (Second Edition) and the ‘Handbook of Pneumatic Conveying Engineering’, both published in 2004. He has been associated with the Powder & Bulk Solids Conference since it began in 1976.
