Powders and Bulk Solids

This book covers powder flow properties, their measurement and applications. A wide range of problems such as flow obstructions, segregation and vibrations are discussed. The content helps to understand the powder flow and provides practical solutions. The fundamentals of bulk solids flow are outlined: 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 and flow agents. The application of the flow properties in the design of properly working bulk solid containers like bins, silos and hoppers is also explored. Besides, the book also covers the technical design of silo walls, feeders, discharge aids, inserts, the assessment of stresses in silos, segregation and how to avoid it and vibrations or shocks occurring in silos
