    Monitoring The Fill Level Of A Ball Mill Using Vibration

    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.
