TL;DR: In this paper, an automatic and efficient strategy can be developed to monitor operating parameters for the control system in a ball grinding circuit using signal measurements, which can be used to obtain a "stereograph" of a ball-grinding circuit.

TL;DR: In this article, a new alternative for monitoring the operating parameters in grinding was developed based on industrial scale measurements, where the mechanical vibration was picked up by an accelerometer and acoustic pressure changes by a microphone.

TL;DR: In this article, a multivariate statistical modeling based on vibration signal analysis was performed at commercial scale grinding, where the source digital signals consist of three channels of mechanical vibrations obtained at the axial, horizontal and vertical directions.

TL;DR: In this paper, the Root-Mean-square and power spectrum were estimated on the time-domain vibration signal using a digital oscilloscope and a partial correlation analysis was applied to the frequency-domain spectrums to detect the non-zero correlation between the frequency bands and the operating parameters in grinding.

TL;DR: In this article, the vibration signal was first picked up with an accelerometer, amplified by a vibrometer and then transmitted to a DAT recorder during the entire testing period.
