Problems solved by technology

Existing detection methods: Vibration method, useful power method, vibroacoustic method, etc. The sensitivity of the detection signal of the vibration method is relatively high, and it can display the change of the material in the ball mill at any time, and is not affected by the surrounding noise source, but it is easily affected by the voltage frequency change , grinding body loss or mill speed and other small fluctuations, it is difficult for the useful power method to judge that the decline of useful power is caused by the overload state of the mill based on the detected signal. However, it is difficult to judge the media filling rate and pulp concentration according to the wear degree of the plate. Although the intelligent material can judge the movement state of the grinding media, it is difficult to judge the material-to-ball ratio and the pulp concentration, and there are various factors affecting the grinding of the grinding machine. The complexity of the coupling between
