This book was released on 2013-07-01 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aims to derive a qualitative model for energy requirements of the wood chipping process. A relationship is shown between energy requirements and properties of biomass, which is a quite variable material.The relationship between comminution machinery and energy which is necessary for the process is highlighted. The derivation of the model is focused on chipping, but it is generally possible to make it available for both different types of biomass (f. ex. agricultural residues)and different types of comminution machinery (f. ex. hammermills) by using different material properties adjusted to the machinery mechanics. The properties which are used in the derivation are meant to be easy to measure. Furthermore, the model is meant to be used as a base for a quantitative model that, thanks to measurements taken from real comminution machinery and thanks to using wood with known properties, could answer two important questions: - Would hypothetical changes in the desired size of output material increase the total system efficiency, taking into consideration the lowest efficiency of the combustion process (e.g., higher amounts of unburned fuel)? - Considering the energy used for the process, how can comminution as an operation in the biofuel supply chain be optimised? Answers for the above questions could highlight new possibilities in terms of further energy savings and a maximising of the energy efficiency of the bioenergy sector. Furthermore, the results could motivate optimized choices of comminution machinery for the biofuel supply chain as well as for other applications. Another important feature of this study is its unique holistic point of view that takes into consideration aspects from the fields of mechanics, material sciences and natural sciences to deliver the full picture to the reader.

Download or read book The Role of Chemical Reactions in the Mechanism of Comminution of Ductile Metals Into Ultrafine Powders by Grinding written by Alan Arias and published by . This book was released on 1968 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: On grinding in pure water, zirconium, tantalum iron and stainless-steel powders were extensively comminuted and simultaneously oxidized with hydrogen release, whereas nickel, copper, and silver powders did not react with water and their particle sizes increased. On grinding nickel, copper, and silver in water pressurized with oxygen nickel and copper became extensively comminuted and were oxidized, whereas silver did not react with oxygen and its particle size increased. From these results and other considerations, it is hypothesized that for extensive comminution of ductile metals and alloys to occur on grinding they must react with the grinding media.

Book excerpt: "Comminution might well be the great technology of the 21st century, yet only a paucity of information exists on the topic. Alban Lynch has taken it upon himself to address this void, assembling an assortment of industry experts to produce the Comminution Handbook. With contributions from the coal, cement, sulfide and industrial mineral industries, as well as mill manufacturing and modelling groups, this work presents an overview of all aspects of comminution, the process of reducing solid materials via crushing and grinding. It comprises 16 chapters structured around the themes of material attributes, processing equipment, circuit design and circuit optimisation and control. The volume will appeal to professionals who are involved in, or have an interest in, comminution, metallurgy and related fields. It is hoped that the book will present comminution as it is today to those who have the responsibility of improving the technology in the future."--Publisher description, viewed AusIMM website, 7 October 2015.

Book excerpt: Bachelor Thesis from the year 2011 in the subject Engineering - Power Engineering, grade: 1,5, Linnaeus University (Bioenergy technology), language: English, abstract: This paper aims to derive qualitative model for energy requirements for wood chipping process. There is relationship shown between energy requirements and properties of biomass, which is quite variable material. Relationship between comminution machinery and energy necessary for the process is highlighted. Derivation of the model is focused on chipping but in general it's possible, to make it available both for different types of biomass (f. ex. agricultural residues) or for different type of comminution machinery (f. ex. hammermills) just by using different material properties adjusted to machinery mechanics. Properties used in derivation are mend to be easy to measure. Model is ment to be used as a base for quantitative model that, thanks to measurements performed on real comminution machinery and using wood with known properties, could give answers for two important questions: - Would hypothetical changes in desired size of output material increase total system efficiency, taking into consideration lowest efficiency of combustion process (i. ex. higher amounts of unburned fuel)? - How to optimise comminution as an operation in biofuel supply chain, with respect to energy used for the process?
Download or read book Foundation Engineering Handbook written by Hsai-Yang Fang and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 935 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than ten years have passed since the first edition was published. During that period there have been a substantial number of changes in geotechnical engineering, especially in the applications of foundation engineering. As the world population increases, more land is needed and many soil deposits previously deemed unsuitable for residential housing or other construction projects are now being used. Such areas include problematic soil regions, mining subsidence areas, and sanitary landfills. To overcome the problems associated with these natural or man-made soil deposits, new and improved methods of analysis, design, and implementation are needed in foundation construction. As society develops and living standards rise, tall buildings, transportation facilities, and industrial complexes are increasingly being built. Because of the heavy design loads and the complicated environments, the traditional design concepts, construction materials, methods, and equipment also need improvement. Further, recent energy and material shortages have caused additional burdens on the engineering profession and brought about the need to seek alternative or cost-saving methods for foundation design and construction.

Download or read book Particle Breakage written by Agba D. Salman and published by Elsevier. This book was released on 2007-11-01 with total page 1241 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
