Powders and Bulk Solids

The book concentrates on powder flow properties, its measurement and applications. These topics are explained starting from the interactions between individual particles up to the design of silos. A wide range of problems are discussed - like flow obstructions, segregation, or vibrations. The goal is to provide a deeper understanding of the powder flow, and to show practical solutions. In the first part are outlined the fundamentals of bulk solids flow: particle-particle interactions, stress, friction, strength, density, flow properties and methods of measurement, shear testers and other test procedures, specific properties of powders and how they are influenced by moisture, temperature, or flow agents. The second part deals with the application of the flow properties on the design of properly working bulk solid containers like bins, silos, and hoppers. Other topics are: the technical design of silo walls, feeders, discharge aids, or inserts, the assessment of stresses acting in silos, segregation and how to avoid it, and vibrations/shocks occurring in silos.Schulze, Dietmar is the author of 'Powders and Bulk Solids', published 2007 under ISBN 9783540737674 and ISBN 3540737677.
