46th ©Annual Canadian Mineral Processors Operators Conference , Ottawa, Ontario, January 21-23, 2014 In the context of fine and ultrafine grinding applications, the use of DEM, CFD and SPH to model stirred mill dynamics holds the promise of determining how all possible variables affect the design and

Effect of the size of media on grinding performance in ...

Highlights Wet grinding in a stirred mill is examined using the CFD-DEM approach. Grinding rate increases with mill speeds but varies slightly with medium size. Grinding rate and total impact energy have a unified correlation. Mill efficiency is characterised by the ratio of impact and input energies. Mill efficiency decreases with increasing medium size.
