Method to measure the fill level of the ball mill Home product method to measure the fill level of the ball mill
Sep 16 2003 The method of monitoring the level of filling of a ball mill which is fed with material to be pulverized and is provided with a drum mounted to rotate on two bearings which are relatively far apart consists in measuring the weight of the drum using strain gauge weight sensors 11 16 under the bearings supporting the drum of the ball mill and comparing the measured weight to a predefined set
