Results indicate that the newly developed nonlinear TubeBall mill model can represent the coal mill dynamics and can be used to predict the mill dynamic performance. 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.

Condition monitoring of the ball mill began in December 2016 and right from the start, the readings indicated potential damage on the output main bearing. As the months passed, the readings remained at a fairly high but stable level, while the BPFO values showed an increasing trend and clear BPFO matches. When the bearing was replaced during a ...
