    The structure-born sound sensor only receives the signal directly on the mill body itself. SMARTFILL is operated in buildings with 16 mills, side-by-side without any interference between the measurement systems. The signals from SMARTFILL can and should be used as set-points in an advanced controller

    Optimization of mill performance by using

    As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
