Abstract Mechanical grinding emits a high-intensity vibration signal that contains information on the mill operating state. Vibration signals from the mill are presented in the form of both mechanical vibration and acoustic pressure. To apply these source signals to monitoring of grinding parameters, industrial scale grinding tests were performed with an iron ore at LKAB, Malmberget.

Abstract The grinding process is characterised by a high number of cutting edges undergoing non-uniform wear, this also typifies a highly non-stationary process. Pure process modelling in order to understand the grinding mechanisms and to predict the work result is difficult. In view of this, several approaches by academia and by industry were made to address this issue.
