noise characteristics of the ball mill

Mill sound detection based on signal singular entropy

Can detect the ball mill load accurately is a key to the success or failure of intelligent control of the whole ball. In the grinding sound signal measurements, the presence of the noise makes signal characteristics can not be extracted exactly, we cannot master the mill load conditions so that the ball mill cannot achieve automatic control.
