Available in PDF, EPUB and Kindle. Book excerpt: flour, potato starch, cracking catalyst, sand, and gravel, one will probably agree that the first four materials definitely are powders and the last one certainly is not. Whether one would call sand a powder probably depends on the partiele size and on personal Vlews. When the astronaut Neil Armstrong returned to the Earth from his trip on the surface of the Moon, he stated: 'The surface is fine and powdery. I can kick it up loosely with my toe. It does adhere in fine layers like powdered charcoal to the sole and inside of my boots. I only go in a small fraction of an inch, but I can see the footprints of my boots and the treads in the fine sandy partieles. ' These words elearly show that the behaviour of powders de pends on the circumstances. In wh at respects are those on the Moon different from those on the Earth? (1) The gravitational force on the surface of the Moon is only one-sixth of that on the Earth. (2) There is no gas on the Moon. The latter aspect means that any water brought there would evaporate and disappear immediately, hence powders on the Moon will always be perfect1y dry so that cohesion between the separate partieles due to liquid bridges will be zero.
Download or read book Fluidization of Fine Powders written by José Manuel Valverde Millán and published by Springer Science & Business Media. This book was released on 2012-10-12 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the rich phenomenology exhibited by fine powders when they are fluidized by a gas flow. Fine powder cohesiveness leads to poor flowability, clumping, difficulty in fluidizing, irregular avalanching behavior, etc. Despite all the inconveniences, fine powder processes pervade the chemical, pharmaceutical, agricultural and mining industries among others. The author in this book analyzes the mechanism by which interparticle adhesive forces are reduced by means of surface additives. Different techniques have been developed in the last years to assist fluidization by helping the gas flow to mobilize and break cohesive aggregates, which help to homogenize fluidization. As reviewed in this book, the use of these techniques may have a relevant impact on novel processes based on fluidized beds of fine powder and with relevant applications on leading edge technologies such as Atomic Layer Deposition on nanoparticles and CO2 capture by gas-fluidized beds of adsorbent powders. The study of fluidized beds has a marked interdisciplinary character. This book is thus intended for academic and industrial researchers in applied physics, mechanical, chemical, and environmental engineering, who are interested in the special characteristics of fine powders.

Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the Proceedings of the November 7-9, 1977 Conference on PROCESSING OF CRYSTALLINE CERAMICS, held at North Carolina State University in Raleigh. It was the Fourteenth in a series of "University Conferences on Ceramic Science" initiated in 1964 and still coordinated by a founding group of four ceramic related institutions, of which North Carolina State University is a charter member, along with the University of California at Berkeley, Notre Dame University, and the New York State College of Ceramics at Alfred University. In addition, two other ceramic-oriented schools, the University of Florida and Case-Western Reserve University, have also hosted Conferences in the series. These research-oriented conferences, each uniquely concerned with a timely ceramic theme, have been well attended by audiences which typically were both inter national and interdisciplinary in character; their published Proceedings have been well received and are frequently cited. This three day conference was concerned with (a) scientific aspects of all process steps which must be combined and controlled effectively and sequentially in producing crystalline ceramics (both oxides and nonoxides), and (b) utilization of these principles in developing processes for several classes of advanced ceramics critical to present and future technology.

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 Metal Powders written by Joseph M Capus and published by Elsevier. This book was released on 2005-12-14 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal powders are just a tiny fraction of the global metals industry, yet they play a key role in such high-profile sectors as cars and consumer electronics. The global value of metal powder consumption has risen since 2000 to over $3.7 billion from under $3 billion. Part of this increase is due to recently escalating primary metal prices. The increase in overall tonnage shipped is in the order of 20%. This fourth edition of Metal Powders: A Global Survey of Production, Applications & Markets 2001 – 2010 has been completely revised to include the most up-to-date information available, in order to provide a coherent picture of the development and status of the metal powder industry. The report is an overview of the production, applications and markets for metal and alloy powders. The market data is presented primarily in terms of tonnages because of the widely different prices of these powders. Markets for each of the metal powder types are discussed in terms of the major application areas. Market data for the main geographical areas are based on industry statistics, supplemented by company annual reports and by private estimates. Other data and forecasts have been compiled from literature surveys, personal visits and telephone interviews.* Review of metal and alloy powder consumption by type of powder and by geographical area* Market forecasts to 2010* Technical overview of metal powder production* Worldwide review of major producers

This book was released on 2013-11-21 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: The necessity of prediction and fine control in the food manufacturing process is becoming more important than ever before, and food researchers and engineers must confront difficulties arising from the specificity of food materials and the sensitivity of human beings to taste. Fortunately, an overview of world research reveals that the mechanisms of the many complex phenomena found in the food manufacturing process have been gradually elucidated by skilful experiments using new analytical tools, methods and theoretical analyses. This book, the proceedings of the 6th International Congress on Engineering and Food (ICEF6), held for the first time in Asia - in Chiba, Japan May 23 -27, 1993 - summarizes the frontiers of world food engineering in 1993. Congress was joined by the 4th International Conference on Fouling and Cleaning. There were 476 active members from 31 countries participating in the Congress. The editors hope that readers will find this book to be a useful review of the current state of food engineering, and will consider future developments in this research field. The editors extend thanks to the members of the organizing committee of ICEF6, and the advisors, Dr. Ryozo Toei, Professor Emeritus of Kyoto University and Dr. Masao Fujimaki, Professor Emeritus of the University of Tokyo. They also acknowledge the international advisory board members who helped the organizing committee in many ways, and the 10 foundations and 66 companies that financially supported the ICEF6. Finally, the editors are indebted to the reviewers of the manuscripts of these proceedings.
