These are the proceedings of the 9th International Conference on Measurement and Control of Granular Materials (MCGM’ 2011), held on the 27 to 29th October, 2011, in Shanghai, China. The 63 peer-reviewed papers are grouped into the chapters: 1: Flow Measurement and Pneumatic Conveying; 2: Measurement of Size, Volume and Other Parameters; 3: Tomographic Technology, Image Processing and Related Sensors; 4: Powder Explosion and System Protection; 5: New Instruments and Sensor Development; 6: Nano and Powder Materials Preparation; 7: Materials Processing and Preparation; 8:Powder Materials Measurement and Processing. Volume is indexed by Thomson Reuters CPCI-S (WoS).

This textbook compiles reports written by about 35 internationally recognized authorities, and covers a range of interests for geotechnical engineers. Topics include: fundamentals for mechanics of granular materials; continuum theory of granular materials; and discrete element approaches.
