We have an application in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 420mA signal or something else in order to determine if the ball is crushing the mineral or the mill lining.
