    Optimization of Cement Grinding Operation in Ball Mills. Contact Us » . Several energy efficient options for cement grinding are available today such as vertical roller mills roller presses (typically in combination with a ball mill) and clinker pre-grinders with ball mills. At present the method for measuring the fill level which used the vibration signal of mill shell shows its advantage compared with other methods. However this method is developed late and the technique for collecting the vibration signal from mill shell is immature. In this paper a novel method for collecting the vibration data from mill shell is proposed.
