Rosenkranz et al. (2011) [ 7] simulated the ball motion in planetary ball mills by DEM modelling technique. They also investigate the effect of important parameters such as ball filling, friction shall, speed, etc. on the ball movement. The obtained results showed a remarkably effect of the friction conditions and ball filling ratio.
Read MoreAn example of simulation for typical spex mill is also given. A new approach to describe comminution processes in general ball mills as a macroscopic canonical ensemble is proposed. Using hamiltonian method, the model is able to take simultaneously into account the internal dynamics from mechanical motions inside the vial and external effects.
