Enlargement and Compaction of Particulate Solids describes the methodology used in the compaction and size enlargement of particulate solids. The discussions are organized into the following topics: characterization of powders and granules before and after compaction; mixing; shear testing; fluidized bed granulation; mechanisms of size enlargement and compaction; and instrumentation of industrial presses and processes. This text is comprised of 12 chapters; the first of which deals with the measurement of size and shape of individual particles or collections of individual particles, both spherical and non-spherical. Attention then turns to particle characterization by size, shape, and surface for contacted particles. The application of nitrogen isotherms Types II and IV and mercury intrusion to compacted solids is highlighted. The chapters that follow focus on powder mixing; flow and handling of solids; and pharmaceutical granulation and compaction. The basic mechanisms of size enlargement are reviewed in relation to three common methods of granulation: pan granulation, fluidized bed granulation, and spray drying or prilling. The remaining chapters describe the mechanisms of compaction, compact characterization, instrumentation of tablet machines, compaction of ceramics, and isostatic pressing and compacting techniques. This book is intended primarily for students and chemical engineers as well as physicists, powder and pharmaceutical technologists, ceramacists, and metallurgists.

Handbook of Powder Technology, Volume 1: Particle Size Enlargement is the first of a series which will together form a Handbook of Powder Technology, primarily intended for engineers and scientists working in industry. The scope of the Handbook can be defined as being concerned with that part of chemical engineering which deals with processes involving the handling and treatment of material in solid particulate form. This book deals with methods used to create larger entities from fine particles so that the bulk properties of particulates can be improved. These so-called ""size enlargement"" methods evidently concern a broad spectrum of technical disciplines and industries ranging from the relatively small scale requirements of pharmaceutical manufacturers through the tonnage requirements of the fertilizer and minerals processing industries. A primary objective in preparing this book was to present a generalized account of the many size enlargement techniques scattered throughout these diverse industries, with emphasis on similarities and unifying characteristics whenever possible. The book devotes one chapter to each of the principal methods used to bring particles together into agglomerates: agitation methods— tumbling agglomeration, agitation methods—mixer agglomeration, pressure methods, thermal methods, spray and dispersion methods, and agglomeration from liquids.

Although agglomeration has long been used in the making of bricks and the recovery of coal particles, scientific investigation in this area only began in the 1950s. Presents for the first time the fundamentals of agglomeration science, the technology related to it and its various applications in modern industry. There is a thorough review of methods of experimental investigation and analysis and a detailed section on industrial size enlargement equipment and processes.

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.

Over half of the products of the chemical and process industries are sold in a particulate form. The range of such products is vast: from agrochemicals to pigments, from detergents to foods, from plastics to pharmaceuticals. However, surveys of the performance of processes designed to produce particulate products have consistently shown inadequate design and poor reliability. `Particle technology' is a new subject facing new challenges. Chemical and process engineering is becoming less concerned with the design of plants to produce generic simple chemicals (which are often single phase fluids) and is now more concerned with speciality `effect' chemicals which may often be in particulate form. Chemical and process engineers are also being recruited in increasing numbers into areas outside their tranditional fields, such as the food industry, pharmaceuticals and the manufacture of a wide variety of consumer products. This book has been written to meet their needs. It provides comprehensive coverage of the technology of particulate solids, in a form which is both accessible and concise enough to be useful to engineering and science students in the final year of an undergraduate degree, and at Master's level. Although it was written with students of chemical engineering in mind, it will also be of use and interest to students of other disciplines. It comprises an account of the fundamentals of teh subject, illustrated by worked examples, and followed by a wide range of selected applications.

Suitable for practicing engineers and engineers in training, this book covers the most important operations involving particulate solids. Through clear explanations of theoretical principles and practical laboratory exercises, the text provides an understanding of the behavior of powders and pulverized systems. It also helps readers develop skills for operating, optimizing, and innovating particle processing technologies and machinery in order to carry out industrial operations. The author explores common bulk solids processing operations, including milling, agglomeration, fluidization, mixing, and solid-fluid separation.
