This book provides powder technologists with laboratory procedures for selecting dispersing agents and preparing stable dispersions that can then be used in particle size characterization instruments. Its broader goal is to introduce industrial chemists and engineers to the phenomena, terminology, physical principles, and chemical considerations involved in preparing and handling dispersions on a commercial scale. The book introduces novices to: - industrial problems due to improper degree of dispersion; - the nomenclature used in describing particles; - the basic physical phenomena, equations, and chemistry involved in particle interactions; - the analytical techniques used for evaluating solid-liquid interfaces - textbooks, courses, societies, and vendors that can provide an advanced understanding of dispersion phenomena. The book provides resources for more experienced technologists by: - discussing characteristics and applications of the various chemical classes of surfactants; - providing procedures for selecting and optimizing a dispersant for a specific solid-liquid system and end-use constraints; - naming typical commercial surfactants and listing the addresses and telephone numbers of their manufacturers; - illustrating the many physical and chemical equilibria that must be considered in modelling a dispersion and guiding the reader to the sources of both data and advanced theoretical treatments required to implement such models. The author has for several years been a consultant in the field of slurry technology, obtaining information, materials, equipment, and expert advice required to solve slurry problems. He also teaches slurry technology and powder dispersion courses to students who are either engineers recently graduated from college or managers recently transferred to plants that handle slurries. His expertise gives the book a wide appeal: as virtually every manufacturing process involves dispersions of powders in liquids, it is of interest to chemists and chemical engineers in industry; the concise definitions, descriptions and examples make it an ideal reference text for teachers and students.

This is the fifth edition of the highly successful work first published in 1968, comprising two definitive volumes on particle characterisation. The first volume is devoted to sampling and particle size measurement, while surface area and pore size determination are reviewed in volume 2. Particle size and characterisation are central to understanding powder properties and behaviour. This book describes numerous potential measuring devices, how they operate and their advantages and disadvantages. It comprise a fully comprehensive treatise on the wide range of available equipment with an extensive literature survey, and a list of manufacturers and suppliers. The author's blend of academic and industrial experience results in a readable technical book with information on how to analyse, present, and extract useful information from data. This is an essential reference book for both industrial and academic research workers in a variety of areas including: pharmaceuticals, food science, pollution analysis and control, electronic materials, agricultural products, polymers, pigments and chemicals.

Particle breakage is an important process within a wide range of solids processing industries, including pharmaceuticals, food, agricultural and mining. Breakage of particles can be defined as intentional and unintentional, depending on whether it is desired or not. Through understanding of the science and underlying mechanisms behind this phenomenon, particle breakage can be either minimised or encouraged within an efficient and effective process. Particle Breakage examines particle breakage at three different length scales, ranging from single particle studies through groups of particles and looking at solid processing steps as a whole. This book is the widest ranging book in the field and includes the most up-to-date techniques such as Distinct Element Method (DEM), Monte Carlo simulations and Population Balance Equations (PBE). This handbook provides an overview of the current state-of-the- art and particle breakage. From the small scale of a single particle, to the study of whole processes for breakage; both by experimental study and mathematical modelling. * Covering a wide range of subjects and industrial applications * Allows the reader an understanding of the science behind engineered breakage processes * Giving an unrestrictive and interdisciplinary approach

Granulation provides a complete and comprehensive introduction on the state-of-the-art of granulation and how it can be applied both in an academic context and from an industrial perspective. Coupling science and engineering practices it covers differing length scales from the sub-granule level through behaviour through single granules, to bulk granule behaviour and equipment design. With special focus on a wide range of industrially relevant areas from fertilizer production, through to pharmaceuticals. Experimental data is complemented by mathematical modelling in this emerging field, allowing for a greater understanding of the basis of particle products and this important industry sector. Four themes run through the book: 1. The Macro Scale processing for Granulation – including up to date descriptions of the methods used for granulation and how they come about and how to monitor – on-line these changes. 2. The Applications of granulation from an industrial perspective, with current descriptive roles and how they are undertaken with relevance to industry, and effective properties. 3. Mechanistic descriptions of granulation and the different rate processes occurring within the granulator. This includes methods of modelling the process using Population – Balance Equations, and Multi-level Computational Fluid Dynamics Models. 4. The Micro Scale: Granules and Smaller, looking at single granules and there interactions and modelling, while also considering the structure of granules and their constituent liquid bridges. * Covers a wide range of subjects and industrial applications * Provides an understanding of current issues for industrial and academic environments * Allows the reader an understanding of the science behind engineered granulation 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.

Handbook of Powder Technology, Volume 4: Dust Explosions presents the dust explosion problem in general terms and describes how and why dusts explode. This book discusses the various approaches used to deal with the dust explosion hazards. Organized into five chapters, this volume begins with an overview of the methods used to assess, remove, or minimize the hazard of dust explosions. This text then examines the factors that influence the initiation and severity of an explosion. Other chapters consider the explosion prevention and explosion protection techniques. This book discusses as well the characteristics of a dust explosion and the historical development of the problem. The final chapter deals with the significant concept of explosion protection to reduce the worst effects of an explosion to an acceptable level. This book is a valuable resource for managers, engineers, scientists, safety personnel, and others involved in the handling ad processing of materials in solid particulate form.
