So far, the main method to measure the ball mill load are direct and indirect methods. The direct method has been put forward in the international mineral processing congress at 1973. The direct method use pole to measure the height of ore pulp liquid level to get the load. It cannot be popularized since the problems of pole damage

At present the method for measuring the fill level which used the vibration signal of mill shell shows its advantage compared with other methods. However, this method is developed late, and the technique for collecting the vibration signal from mill shell is immature. In this paper, a novel method for collecting the vibration data from mill shell is proposed.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or
