The paper presents a newly developed nonlinear TubeBall mill model for model based online condition monitoring. This mathematical model is derived through analyzing energy transferring, heat exchange and mass flow balances. Evolutionary techniques are adopted to identify the unknown system parameters using the onsite measurement data. The identified system parameters are then validated ...
