### A Mathematical Model for Predicting the Internal

The internal parameters of ball mill are very important in the grinding process and have significant impact on the grinding results. Accurate measurement of the internal parameters of ball mill is crucial and indispensable for optimization and control of grinding process. In this paper, a novel trisensor measurement method was used to measure the external signals (i.e., bearing pressure
