Fill level measurement device for ball mill

Oct 19, 2019 The ball mill fill level is an important process parameter and it is difficult to accurately measure it. In this paper, a new approach is presented for ball mill fill-level estimation. A three-layer neural network is used here along with various vibration signal processing techniques as a novel ball mill fill-level estimation method

    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

    1. The fill level in the mill was set equal to an arbitrary value of 80 % when the mill reached normal operating conditions (i.e. stable circuit conditions at an ore feed rate of 90 tonnes per hour). The arbitrary fill level of 80 % does not necessarily mean that the mill is 80 % full of ore and grinding media
