The paper is devoted to the study of the relationship between the vibration accelerometer signal and the fill level of a ball mill. It was established that there is a direct correlation between the vibration level of the front support of the mill drum and the amount of material being ground in the mill. A low vibration level corresponds to a high fill level of the mill. Two methods of processing the vibration accelerometer signal to obtain a fill level signal using a moving window are proposed.

The work of the control system of ball mill electric drive during the start-up process is analyzed using computer simulation. The developed computer model uses the variable nonlinear model of the mechanical load and the variable moment of inertia. The results of the conducted researches can be used at development of new systems of electric drives.
