Cascade Separation of Powders

0.0

The authors describe the theoretical work and practical results obtained in recent years in the area of separation of powders in moving flows. The promising nature of the cascade separation method is stressed. Mathematical models of regular, combined and irregular cascades are described. Mathematical fundamentals of the structural, dynamic and kinetics models of the process are presented. A new approach to optimising the separation processes, based on the separation curves and information theory, is explained. Experience with the industrial application of cascade classifiers is presented. The main relationships obtained for cascade processes are of the phenomenological nature and can be used for cascade processes such as rectification, extraction, separation of isotopes, cascade drying of bulk materials, etc. The book is suitable for scientists and engineering working on various aspects of powder technology and ore enrichment. It may also be used as a textbook for university and college students in the area of mining, engineering chemistry, metallurgy, energetics, constructional engineering, etc.

Michael Barsky was born in 1936. He graduated in Mechanical Engineering from the Ural State Technical University of Katerinburg, Russia in 1960. He received his Ph.D. degree in 1964 and D.Sc. degree in 1971. In 1973 he was appointed the full professor. In 1990 he joined the staff of Ben-Gurion University of the Negev, Beer-Sheva, Israel. Professor Barsky’s scientific interests lie in mass processes, separation of free-flowing materials in air and gaseous streams, dynamics of two-phase flows in critical regimes and physical foundations of flows of this type. Professor Barsky is the author of three books and of more than 200 scientific papers. Eugene Barsky was born in 1974. He graduated in 1993 from Ben-Gurion University, Beer-Sheva, Israel, with a B.Sc. degree in mathematics. Thereafter, he received his M.Sc. degree in 1998 and Ph.D. degree in 2001 in Industrial mathematics.In 2002, he become a staff member of the Negev Academic College of Engineering. Beer-Sheva, Israel. His scientific interests lie in the mathematical modelling of technological Processes, optimisation and combinatorics. Dr. Barsky has published 15 articles.
