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 methodget price
Results of the paired-sample's t-test showed that mean risk rating differs before taking control measures (M = 9.13, SD = 5.99) and after taking control measures (M = 2.80, SD = 1.38) at the 0.0001 level of significance (t = 12.6428, df = 115, N = 116, P 0.0001, 95% CI for mean difference 5.34 to 7.32). On an average, risk reduction was aboutget price
Abstract. Investigation of a dry fine grinding circuit has shown significant influence of the mill load (powder filling) on the production capacity. To improve the circuit performance at industrial scale, alternative ways of mill load measurement were investigated.

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, isget price
