Modeling comminution processes in ball mills as a canonical ensemble

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 like electromagnetic and gravitational forces. Relevant physical observables are extracted using statistical mechanics approach through partition function at finite temperature. The method enables numerical calculation using Monte Carlo technique to obtain, for instance particle number evolution in term of system temperature. It is argued that the method is experimentally more verifiable than the conventional approaches based on geometrical displacements. An example of simulation for typical spex mill is also given.

Preliminary simulation of temperature evolution in comminution processes in ball mills

A model for comminution processes in ball mills is presented. The model provides an empirical approach using the physically realistic modelization of the ball mill system, but also deployes the statistical method to extract relevant thermodynamics observables. Those physical observables are investigated by treating the whole system as a statistical macroscopic ensemble.

Extracting physical observables using macroscopic ensemble in the spex-mixer/mill simulation

A technique to simulate the spex-mixer/mill system as a macroscopic ensemble rather than a pure dynamical system is proposed. The treatment is suitable especially for comminution processes generating the nanomaterial up to nanometers scale where the geometrical displacements are unobservable. It is argued that the method is simple and experimentally verifiable since relevant physical observables can be extracted using partition function without solving the equation of motions.
