This report concerns international overview and outlook on comminution technology for effective production of mineral powders in order to improve the product quality and reduce the energy consumption. These involve new and improved grinding mills (roller mills, stirred media mills, vibration mills, centrifugal mills, jet mills etc) and high performance classifiers (air classifiers and centrifuges) as well as their industrial applications. The possible utilization of other assisted techniques like chemical, or microwave or ultrasonic energies to grinding processes as also been described. In addition, this report presents recent international work and outlook on modern methods for on/in-line control/analysis, modelling and simulation for optimization of grinding production.
