The development of the socalled "electronic ear" SmartFill system started around the year 2000 and was under continuous enhancement and adaptation to modern requirements over the last few years. SmartFill was, and is, a serious revolution in sensor technology as a highprecision, interferencefree level measurement method in ball mills ...
The fill level of the ball mill is optimised according to the production requirements. The fill level is measured by an electronic ear. Our new system captures a broad spectrum of frequencies which simplifies the filtering of external sources such a neighbouring mills. The ear measures and memorises the frequencies of each mill.
Therefore, it is possible to send information regarding the strain in the mill shell not only when the strain transducer is on the top and on the bottom of the mill, but also during the mill revolution. Mill charge in grinding ball mill circuits 1335 The signal from the receivers is sent to the control room.

Condition monitoring of the ball mill began in December 2016 and right from the start, the readings indicated potential damage on the output main bearing. As the months passed, the readings remained at a fairly high but stable level, while the BPFO values showed an increasing trend and clear BPFO matches.
The reference level is typically set at the threshold of perception of an average human and there are common comparisons used to illustrate different levels of sound pressure. As with other decibel figures, normally the ratio expressed is a power ratio (rather than a pressure ratio). The human ear has a large dynamic range in audio perception.
