Pneumatic Conveying Of Solids

Pneumatic conveying is one of the most popular methods of handling bulk powdered and granular materials in mining, chemical and agricultural industries. This 3rd edition of this successful book covers both theoretical and practical aspects of the subject. It is unique in its blending of academic materials and good industrial design techniques. Each topic is covered in depth, with emphasis placed on the latest techniques, hardware systems and design and research methodology. Its comprehensive worked examples and table ensure that the reader need not consult any other reference material. In this 3rd edition new sections on simulation and modelling have been added, while the use of tomography as a tool for monitoring pneumatic conveying is also covered.

When the four of us decided to collaborate to write this book on pneumatic conveying, there were two aspects which were of some concern. Firstly, how could four people, who liveon four different continents, write a book on a fairly complex subject with such wide lines of communications? Secondly, there was the problem that two of the authors are chemical engineers.It has been noted that the majority of chemical engineers who work in the field of pneumatic conveying research have spent most of their time considering flow in vertical pipes. As such, there was some concern that the book might be biased towards vertical pneumatic conveying and that the horizontal aspects (which are clearly the most difficult!) would be somewhat neglected. We hope that you, as the reader, are going to be satisfied with the fact that you have a truly international dissertation on pneumatic conveying and, also, that there is an even spread between the theoretical and practical aspects of pneumatic conveying technology.

Pneumatic Conveying Design Guide is a guide for the design of pneumatic conveying systems and includes detailed data and information on the conveying characteristics of a number of materials with a wide range of properties. This book includes logic diagrams for design procedures and scaling parameters for the conveying line configuration. It also explains how to improve the performance of pneumatic conveyors by optimizing, uprating, and extending the system or adapting it for a change of material. This book consists of 15 chapters divided into three sections and opens with an overview of the state of the art on pneumatic conveying, along with definitions of the terms used in pneumatic conveying. The next chapter describes the various types of pneumatic conveying systems and the parameters that influence their capabilities in terms of material flow rate and conveying distance. The discussion then turns to feeding and discharging of the conveying line; selection of a pneumatic conveying system for a particular application; and design procedures for pneumatic conveying system. The theory and use of compressed air in pneumatic conveying are also considered, along with the effect of material properties on conveying performance; troubleshooting; and operational problems and some solutions. The final chapter is devoted to the use of bench-scale test methods to determine the material properties relevant to pneumatic conveying. This monograph is intended for designers and users of pneumatic conveying systems.

This handbook presents comprehensive coverage of the technology for conveying and handling particulate solids. Each chapter covers a different topic and contains both fundamentals and applications. Usually, each chapter, or a topic within a chapter, starts with one of the review papers. Chapter 1 covers the characterization of the particulate materials. Chapter 2 covers the behaviour of particulate materials during storage, and presents recent developments in storage and feeders design and performance. Chapter 3 presents fundamental studies of particulate flow, while Chapters 4 and 5 present transport solutions, and the pitfalls of pneumatic, slurry, and capsule conveying. Chapters 6, 7 and 8 cover both the fundamentals and development of processes for particulate solids, starting from fluidisation and drying, segregation and mixing, and size-reduction and enlargement. Chapter 9 presents environmental aspects and the classification of the particulate materials after they have been handled by one of the above-mentioned processes. Finally, Chapter 10 covers applications and developments of measurement techniques that are the heart of the analysis of any conveying or handling system.

An understanding ofthe properties and the handling characteristics of liquids and gases has long been regarded as an essential requirement for most practising engineers. It is therefore not surprising that, over the years, there has been a regular appearance of books dealing with the fundamentals of fluid mechanics, fluid flow, hydraulics and related topics. What is surprising is that there has been no parallel development of the related discipline of Bulk Solids Handling, despite its increasing importance in modern industry across the world. It is only very recently that a structured approach to the teaching, and learning, of the subject has begun to evolve. A reason for the slow emergence of Bulk Solids Handling as an accepted topic of study in academic courses on mechanical, agricultural, chemical, mining and civil engineering is perhaps that the practice is so often taken for granted. Certainly the variety of materials being handled in bulk is almost endless, ranging in size from fine dust to rocks, in value from refuse to gold, and in temperature from deep-frozen peas to near-molten metal.

Abbreviated Guide: Pneumatic Conveying Design Guide describes the selection, design, and specification of conventional pneumatic conveying systems. The design procedure uses previous test data on the materials to be conveyed. The book also discusses system economics, operating costs, the choice of appropriate components or systems, system control, and system flexibility. The design system involves the type of conveying system for installation, the pipeline parameters, and also the plant components. System selection covers the properties of the material to be conveyed, plant layout, material properties, as well as whether an open system or a closed system is more appropriate. In pipeline design, the engineer should consider the bore of the pipeline, the air requirements in terms of delivery pressure and volumetric flow rate. Based on this data, he can determine the rating of the air mover to achieve the optimal material flow rate. From the pipeline design study, the engineer can then evaluate all the necessary operating parameters at each pipeline bore to identify plant component specifications. He can then compute for the costs of the components and operating costs of the system. Engineers, technicians, and investigators involved in industrial pneumatic conveyance will find the book highly useful.
