High-frequency indication of the mill fill level vectors that can be used to improve mill operation. ...

The paper proposes a novel soft sensor based on uncertainty reasoning of cloud model to improve the accuracy and reliability of fill level measurement and shows that the accuracy of proposed method can meet the requirements of field measurement applications. Considering the strong uncertainty in ball mills, cloud model which combines fuzziness and randomness …

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.

various ball load and water content of coal conditions were conducted in an industrial mill to investigate the relationship between the fill level and the angular position of the maximum …

Based on the cloud model, a mathematical tool which has the property of stable tendency and the ability to organically combine the fuzziness and the randomness of the data, a method is proposed to represent the concepts of fill level and efficiently measure the fill level in ball mill. The vibration signals of ball mill bearing are found to be highly divergent and strongly stochastic …

The static and dynamic grinding media's voidage inside the ball mills were studied to improve the Morrell-C model's accuracy in predicting the ball mills' power draw. The three-level factorial design with two independent variables, including fractional filling and mill rotating speed, was used to design experiments, examine the effects of ...

Using a three-level factorial design, we provided an empirical model to determine the voidage of each ball size distribution proposed by Bond for ball mills' first filling in various ranges of ...

Ball mills are extensively used in the size reduction process of different ores and minerals. The fill level inside a ball mill is a crucial parameter which needs to be monitored regularly for ...

The exact measurement of the fill level is the key and basic problem for automatic control and optimized operation of the coal pulverizing system. Because the ball mill pulverizing system is non-linearity, long time delay and time-varying, the reliable and effective method for measuring the fill level was lacked at present. In order to reduce the influence by various factors on measuring …
