As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
the mill to yield two real-time volumetric fill levels along with another fill level measurement taken from the mill shell. Examples of these results have been documented in a previous SAG mill ... The ball mills are also operated in a closed circuit employing two hydrocyclone separators. The

Zhang (2001) studied the fill level by measuring the energy consumption of the mill motor, but the wear of steel balls and the variation of ball load can seriously affect the power value of the mill. Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell.

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.

Introduction: Ball mill grinding sound level measuring system receive the ball mill sounds by using special sensor, then transfer the signal through shielded cable to instrument, convert the signal into percentage display on the screen, at the same time output 4~20mA current signal for DCS system.
The exact measurement of the fill level is the key and basic problem for automatic control and optimized operation of the coal pulverizing system. Because the ball mill pulverizing system is non-linearity, long time delay and time-varying, the reliable and effective method for measuring the fill level was lacked at present.

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...
One main reason is that fill level in ball mill is hardly measured precisely. Different from other ANNs, the learning velocity of CMAC is far more rapid. The ball mill Measurement and control system is designed in this paper. CMAC is used to measure and control fill level in this system. And some problems during realization are solved.1.
Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell. When the transducer moved to the top position of the mill shell, it measured the compression. After half a revolution, the transducer reached the bottom of the mill shell, the tension being measured.
