Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geomathematics 4: Sampling of Particulate Materials: Theory and Practice reviews the theory and practice of sampling particulate solids, such as ores and concentrates. With examples borrowed from the mining, metallurgical, and cement industries, the book examines particulate materials of vegetable and mineral origin, including cereals, oil seeds, sugar beets, granulated drosses or slags, bars, plates, and ingots. Organized into nine parts encompassing 34 chapters, this volume begins with an overview of the theory of sampling and sampling-error generating mechanisms. It then discusses the continuous selection and discrete models of the increment sampling process and the materialization of punctual increments. It explains the splitting process and its practical implementation in sampling. Lot and sample preparation, resolution of sampling problems, and problems associated with commercial sampling are also discussed. The book also describes the detection of measurement or sampling biases and inconspicuous losses of material, and the design of automatic sampling plants. This book is a valuable resource for geologists, mining engineers, metallurgists, and analysts.

Download or read book Guidance for Obtaining Representative Analytical Laboratory Subsamples from Particulate Laboratory Samples written by National Exposure Research Laboratory (U.S.) and published by . This book was released on 2003 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ongoing research program has been established to experimentally verify the application of the Gy theory to environmental samples, which serves as a supporting basis for the materials presented in this guidance. Research results from studies performed by the United States Environmental Protection Agency (U.S. EPA) have confirmed that the application of the Gy sampling theory to environmental heterogeneous particulate materials is the appropriate state-of-the-science approach for obtaining representative laboratory subsamples. This document provides general guidelines for obtaining representative subsamples for the laboratory analysis of particulate materials using the 'correct' sampling practices and the 'correct' sampling devices based on Gy theory. Besides providing background and theory, this document gives guidance on: sampling and comminution tools, sample characterization and assessment, developing a sampling plan using a general sampling strategy, and reporting recommendations. Considerations are given to: the constitution and the degree of heterogeneity of the material being sampled, the methods used for sample collection (including what proper tools to use), what it is that the sample is supposed to represent, the mass (sample support) of the sample needed to be representative, and the bounds of what 'representative' actually means. A glossary and a comprehensive bibliography have been provided, which should be consulted for more details.
Download or read book Gy s Particulate Material Sampling Theory written by RA. Bilonick and published by . This book was released on 1990 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: An outline of Gy's contributions to particulate material sampling is presented. Gy's theory provides a comprehensive framework that integrates all aspects of sampling particulate materials such as coal, ores, pulps, industrial and municipal effluents, and environmental contaminants. The theory defines and quantifies the two types of heterogeneity (constitution and distribution) and shows how they can be empirically measured using either expensive variographic information or often more readily available size--density information. These results provide principles for constructing sampling devices free from bias and excessive noise. They also provide practical methods for realistically estimating sampling precision for both increment processes (e.g. cross-stream samplers) and splitting processes (e.g. riffle splitters) without requiring significant additional work. The theory also provides practical methods for investigating the potential bias in sampling equipment and methods.
Download or read book Particle Size Measurements written by Henk G. Merkus and published by Springer Science & Business Media. This book was released on 2009-01-07 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the practical aspects of particle size measurement: a major difference with existing books, which have a more theoretical approach. Of course, the emphasis still lies on the measurement techniques. For optimum application, their theoretical background is accompanied by quantitative quality aspects, limitations and problem identification. In addition the book covers the phenomena of sampling and dispersion of powders, either of which may be dominant in the overall analysis error. Moreover, there are chapters on the general aspects of quality for particle size analysis, quality management, reference materials and written standards, in- and on-line measurement, definitions and multilingual terminology, and on the statistics required for adequate interpretation of results. Importantly, a relation is made to product performance, both during processing as well as in final application. In view of its set-up, this book is well suited to support particle size measurement courses.
Download or read book Sampling of Particulate Materials written by Bastiaan Geelhoed and published by IOS Press. This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is a Ph.D. thesis. There are many chemical, physical or biological properties of solid materials that are of crucial importance for economic, agricultural, environmental or health-related reasons. These properties are often estimated using chemical, physical or biological tests on one or more laboratory samples. During the drawing of the bulk sample from which the laboratory sample is extracted, sampling errors can occur. These sampling errors are caused by the sampling of non-identical particles. Contents include: Introduction, Review of current sampling theories, Size-based multinomial selections: a model for sampling, Size-based sampling theory, Estimation of the variance of the sample concentration, Evaluation of bias, Experimental evaluation of the theory developed, Minimum sample mass, Final remarks."

Download or read book Theory of Particulate Processes written by Alan Ranodolph and published by Elsevier. This book was released on 2012-12-02 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theory of Particulate Processes: Analysis and Techniques of Continuous Crystallization, Second Edition covers the numerous population balance-based particulate studies. This edition emerged from the notes for an industrial short course on crystallization. This book is divided into 10 chapters and begins with an outline of the methods for representation of particle distributions and a systematic approach to the predictive modeling of processes where there is a need to characterize distributions in time and space and by some identifying property. The succeeding chapters provide a specific and more elementary approach to modeling crystal size distributions, as well as the modeling the kinetics of crystal nucleation and growth rates. Other chapters discuss a wide range of system analysis and design considerations specific to crystallization for both the steady state and unsteady state. The final chapters illustrate the use of a population balance analysis to interpret data from both laboratory and process equipment. These chapters also explore a wide variety of particulate processes and systems for which the population balance analysis is useful. This book is of great value to graduate students with particulate systems course.
