Optimization and Design of Grinding Process by Computer Simulation

Abstract

Grinding is a unit operation to reduce particle size by milling, and recently the demands for such operations have been increasing more and more. Computer simulation is effective in optimizing the grinding process and designing equipment, and the number of studies is increasing. To predict grinding results quickly with a low calculation load, it is useful to output the impact energy obtained from ball-only calculations as an indicator of grinding. We introduce how simulation can be used in grinding process analysis, including examples of reproducing ball behavior, predicting grinding results such as particle size distribution, and analyzing mechanochemical effects.
