The paper presents a newly developed nonlinear tube-ball mill model for model based on-line 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 on-site measurement data. The identified system parameters are then validated

Within the classification there are also two versions of the Morrell C-model

Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface. This is the rotational speed where balls will not fall away from the mill s shell.
