A wide range of problems are discussed – such as flow obstructions, segregation, and vibrations. The goal is to provide a deeper understanding of the powder flow, and to show practical solutions.
Download or read book Characterization of Powders and Aerosols written by Brian H. Kaye and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of fine particles is a difficult task! A large number of industries deal with materials in powder form. The properties of these powders depend on their particle size, particle shape and size distributions, surface and porosity. What are the methods? What are the problems? What questions need answering? This new book covers the problems of sampling both powders and aerosols, and discusses calibration standards for different instruments. It takes into account fractionating methods for fine particles, e.g., sieving procedures, sedimentation methods, and the use of cyclones. Image analysis and its use for the measurement of the size and shape of powder grains and light-diffraction techniques for size evaluation are presented. Furthermore, this books covers the most effective methods for measuring surface areas, fractal structures of rough surfaces, and pore structures of porous bodies. Practitioners will find tips for modification of analytical procedures for on-line characterization, and many graphs for comparing data obtained by different methods are presented.
Download or read book Development of Predictive Tools for the Characterisation of Milling Behaviour of Pharmaceutical Powders Entwicklung Von Methoden Zur Vorhersage Der Zerkleinerungseigenschaften Pharmazeutischer Pulver written by Matthias Meier and published by Logos Verlag Berlin GmbH. This book was released on 2010 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work examines the main influence factors on the breakage behaviour of pharmaceutical substances and other organic crystals. Particle surface characterisation is done via Atomic Force Microscopy, thus examining the transport properties of the powders. The breakage behaviour is characterised by single particle impact experiments. Mechanical properties are determined by indentation. The results show a clear correlation between the breakage behaviour -- expressed by the breakage probability and the breakage function -- and the hardness and fracture toughness of the material. This allows an estimate about the breakage behaviour of a substance from indentation experiments with far less material consumption than in conventional milling experiments.
Download or read book Characterisation of Bulk Solids written by Don McGlinchey and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handling of powders and bulk solids is a critical industrial technology across a broad spectrum of industries, from minerals processing to bulk and fine chemicals, and the food and pharmaceutical industries, yet is rarely found in the curricula of engineering or chemistry departments. With contributions from leading authors in their respective fields, Characterisation of Bulk Solids provides the reader with a sound understanding of the techniques, importance and application of particulate materials characterisation. It covers the fundamental characteristics of individual particles and bulk particulate materials, and includes discussion of a wide range of measurement techniques, and the use of material characteristics in design and industrial practice. The reader will then be in a better position to diagnose solids handling and processing problems in industry, and to deal with experts and equipment suppliers from an informed standpoint. Written for post-graduate engineers, chemical scientists and technologists at all stages of their industrial career, the book will also serve as an ideal primer in any of the specialist areas to inform further study.
Download or read book Characterization of Porous Solids and Powders Surface Area Pore Size and Density written by Seymour Lowell and published by Springer Science & Business Media. This book was released on 2006-04-24 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of interest in newly developed porous materials has prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. One might consider this new book as the 4th edition of "Powder Surface Area and Porosity" (Lowell & Shields), but for this new edition we set out to incorporate recent developments in the understanding of fluids in many types of porous materials, not just powders. Based on this, we felt that it would be prudent to change the title to "Characterization of Porous Solids and Powders: Surface Area, Porosity and Density". This book gives a unique overview of principles associated with the characterization of solids with regard to their surface area, pore size, pore volume and density. It covers methods based on gas adsorption (both physi and chemisorption), mercury porosimetry and pycnometry. Not only are the theoretical and experimental basics of these techniques presented in detail but also, in light of the tremendous progress made in recent years in materials science and nanotechnology, the most recent developments are described. In particular, the application of classical theories and methods for pore size analysis are contrasted with the most advanced microscopic theories based on statistical mechanics (e.g. Density Functional Theory and Molecular Simulation). The characterization of heterogeneous catalysts is more prominent than in earlier editions; the sections on mercury porosimetry and particularly chemisorption have been updated and greatly expanded.

Download or read book Powder Surface Area and Porosity written by Seymour Lowell and published by Springer Science & Business Media. This book was released on 1991-05-31 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of interest in powders and their surface properties in many diverse industries prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. It is intended as an introduction to some of the elementary theory and experimental methods used to study the surface area, porosity, density, and particle size of powders. It may be found useful by those with little or no training in solid surfaces who have the need to learn quickly the rudiments of surface area, density, pore size, and particle size measurements. S.

Download or read book Powder Metallurgy Evaluation and Correlation of the Quality Characteristics of Powdered Iron Compacts written by A. Squire and published by . This book was released on 1944 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The values of the quality characteristics of iron powder compacts were found to be dependent upon the material from which the compacts are formed and the processing operations which they subsquently receive, Impact strength is particularly sensitive to changes in material and processing. It is possible to evaluate the porosity and porosity distribution within powder compacts by means of radiogrphic technique. Data obtained in the determination of certain quality characteristics may be used as a measure of related characteristics, Useful relationships were fopund between tensile strength and shear strength, tensile strength and bend strength, and elongation and bend angle. The uniformity and reproducilibility of results were determined by the testing of a limited number of specimens. Particularly close values were obtained for tensile and shear properties but results for the bend properties of resintered materials were rather undependable.
