New sensor system for ball mill control.

 · * The ratio LRF for an empty mill to the LRF for a full mill, measured by the sensor, is more than a factor of 10, even at a relatively low frequency ( for example, below 500 Hz ). By way of comparison, under the same conditions an acoustic sensor shows insignificant changes in frequency and, in amplitude, a change of only 3 or 4 times at a relatively high frequency ( over 500 Hz ).
