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

Drawing from the third edition of the bestselling Powder Technology Handbook, this book is focused solely on analyzing the fundamental properties and behavior of particles and particle beds. Powder Technology: Fundamentals of Particles, Powder Beds, and Particle Generation concentrates on the most useful analytical methods of observation, measurement, modeling, and prediction. This volume carefully incorporates the progressive work and vision of new authors while retaining the concepts that continue to promote innovative research and applications. The authors highlight new information and developments from areas including surface properties and analysis, particle motion in fluids, mechanical properties of a powder bed, and the design and formation of composite particles. They explain how particles deposit, coagulate, and settle in various media, explore different techniques for generating particles in different states, and detail methods of surface modification. Particularly useful for scientists studying nanoparticle applications, Powder Technology: Fundamentals of Particles, Powder Beds, and Particle Generation incorporates the latest developments in areas including surface properties and analysis, particle motion in fluids, mechanical properties of a powder bed, and the design and formation of composite particles.

Particle Technology and Engineering presents the basic knowledge and fundamental concepts that are needed by engineers dealing with particles and powders. The book provides a comprehensive reference and introduction to the topic, ranging from single particle characterization to bulk powder properties, from particle-particle interaction to particle-fluid interaction, from fundamental mechanics to advanced computational mechanics for particle and powder systems. The content focuses on fundamental concepts, mechanistic analysis and computational approaches. The first six chapters present basic information on properties of single particles and powder systems and their characterisation (covering the fundamental characteristics of bulk solids (powders) and building an understanding of density, surface area, porosity, and flow), as well as particle-fluid interactions, gas-solid and liquid-solid systems, with applications in fluidization and pneumatic conveying. The last four chapters have an emphasis on the mechanics of particle and powder systems, including the mechanical behaviour of powder systems during storage and flow, contact mechanics of particles, discrete element methods for modelling particle systems, and finite element methods for analysing powder systems. This thorough guide is beneficial to undergraduates in chemical and other types of engineering, to chemical and process engineers in industry, and early stage researchers. It also provides a reference to experienced researchers on mathematical and mechanistic analysis of particulate systems, and on advanced computational methods. Provides a simple introduction to core topics in particle technology: characterisation of particles and powders: interaction between particles, gases and liquids; and some useful examples of gas-solid and liquid-solid systems Introduces the principles and applications of two useful computational approaches: discrete element modelling and finite element modelling Enables engineers to build their knowledge and skills and to enhance their mechanistic understanding of particulate systems

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.
