Abstract [en]

During mechanical grinding high-intensity vibration is emitted that contains information on the operating state of the mill. To study the influence of operating parameters on the vibration signature tests were performed with a laboratory ball-mill. Five operating parameters were considered: mill speed, powder filling (as a percentage of voidage), pulp density, grinding period, and pulp temperature. Vibration signals were detected by an accelerometer, amplified by a portable vibrometer and recorded with a digital audio tape recorder. A digital oscilloscope was used to convert the signals into an IBM-compatible data format.
