Ball mills fill level monitoring. One of the greatest research efforts in improving the efficiency of ball mills has focused on the monitoring of the fill level. For a given amount of steel balls, it is not desirable that the mill is too full or too empty of grinding material. If the fill level of ore grinding is low, most of the
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.
