method to measure the fill level of the ball mill

New Method to Measure the Fill Level of the Ball Mill Ⅱ ...

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 the fill level and improve the measuring accuracy of the fill level, a novel characteristic variable is proposed.

Monitoring the fill level of a ball mill using vibration ...

2019-10-19  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.

Optimization of mill performance by using

2015-4-16  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

Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
