The Pneumatic Conveying Design Guide will be of use to both designers and users of pneumatic conveying systems. Each aspect of the subject is discussed from basic principles to support those new to, or learning about, this versatile technique.

The Guide includes detailed data and information on the conveying characteristics of a number of materials embracing a wide range of properties. The data can be used to design pneumatic conveying systems for the particular materials, using logic diagrams for design procedures, and scaling parameters for the conveying line configuration. Where pneumatic conveyors already exist, the improvement of their performance is considered, based on strategies for optimizing and up-rating, and the extending of systems or adapting them for a change of material is also considered.

All aspects of the pneumatic conveying system are considered, such as the type of material used, conveying distance, system constraints including feeding and discharging, health and safety requirements, and the need for continuous or batch conveying.

Key Features

  • Highly practical, enabling suppliers and users to choose, design, and build suitable systems with a high degree of confidence
  • Health and safety requirements taken into consideration in the safe conveying methods described in this book
  • Practical application combined with background theory makes this an excellent resource for those learning about the topic


Design, plant, maintenance and process engineers, industrial engineers and manufacturers in process industries. Library reference for universities teaching postgraduate courses on Bulk Solids Handling.

"Excellent practical data for industry. There is some outstanding content in this book - data and insights that are very hard to find elsewhere". T. A. Bell, Dupont, USA "The book contains detailed practical knowledge, much of which is of direct benefit to industry. Although aimed at professional engineers, most technically competent personnel in the process industires will find the book of value. In summary, the book contains much mateial of real value to the target audience. Good guidelines an advice of a practical nature backed up by sound principles". Prof. M. Jones, The University of Newcastle, Centre for Bulk Solids and Particulate Technologies, Callaghan, Australia. "The text blends theory with application and strategically uses case studies to illuminate good industrial design practices, which will be invaluable to the practitioner...This new edition is not just a reissue of the first edition with cosmetic changes. All the chapters have been updated and greatly expounded is a desirable easy to use reference book." - E-Streams, Vol. 8, No. 5 - May 2005
