Advances in Comminution comes at a critical time. It focuses on the dilemma of needing to grind materials to ever-finer sizes while maintaining reasonable energy costs. The selection and sizing of stirred mills for regrinding and ultrafine grinding applications do not lend themselves to conventional methodologies; therefore, new approaches are being developed.

There is a great deal of activity directed toward improving ore characterization to predict AG/SAG mill energy requirements, as well as developing improved models and instrumentation for optimization and control of comminution circuits. Instrumentation, modeling, and control functions in particular have benefited from rapidly advancing computer technology, with calculations that were formerly extremely time-consuming becoming rapid and routine. These advances will keep energy waste to a minimum and will provide the increased energy efficiency needed to maintain ongoing industry success.

The 36 chapters are based on the 2006 SME symposium. Topics and contributors were carefully selected to provide a balance between academic and industrial practice so that the reader can readily find information on current best practices and evaluate future industry trends.

Review, SciTech Book News, June 2006

Thirty-six papers from the 2006 conference report advances in comminution technologies and practices, breakage, mill design, instrumentation, modeling, and simulation. Several of the papers discuss recent experiences with high-pressure grinding rolls, ultrafine grinding, autogenous grinding (AG) and semiautogenous grinding (SAG). Other topics include inflections in hydrocyclone efficiency curves, the influence of slurry theology on stirred media milling of limestone, the selection of mill liners, the gearless mill drive, and ball mill circuit models for improving plant performance.
