Macroscopic simulation for the internal dynamics of nano processes in ball mills

Numerical simulation for comminution processes inside the vial of ball mills are performed using Monte Carlo method. The internal dynamics is represented by recently developed model based on hamiltonian involving the impact and surrounding electromagnetic potentials. The paper is focused on investigating the behaviors of normalized macroscopic pressure, $P/{P_0}$, in term of system temperature and the milled powder mass. The results provide theoretical justification that high efficiency is expected at low system temperature region. It is argued that keeping the system temperature as low as possible is crucial to prevent agglomeration which is a severe obstacle for further comminution processes.
