Nov 01, 2009· 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.

More### New Method to Measure the Fill Level of the Ball Mill I

Abstract: Up to now, the accurate measurement of the fill level in the ball mill hasn’t been resolved because of the interplay of many variable factors, which led the mill to be operated under the uneconomical condition and lost a lot of energy. At present, some methods, such as vibration method and acoustic method, have been applied for measuring the fill level by the researchers.

More### Optimization of mill performance by using

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

More### Mill Steel Charge Volume Calculation

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

More### Development of a method to measure charges in tumbling mills

On the S width method, small direct measurement differences cause big variations on the charge level estimatives and the trend of such errors is to increase in smaller diameter mills, which is the case of the measured ball mill. The MCP eliminates vague criterias adopted by people while measuring mill internally by common methods.
