20041013Calculation of the power draw of dry multicompartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11.The feed can be dry with less than 3 moisture to minimie ball coating or slurry containing 2040 water by weight.
2012710The design of a ball mill can vary significantly depending on the sie the equipment used to load the starting material feeders and the system for discharging the output product. The sie of a mill is usually characteried by the charge in the mill and a different impact of the milling bodies on the ground material. The grinding process
Ball Sie as Initial Charge. Commercial ball sies 10 150 mm Number sie and mass of each ball sie depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill Coghill and DeVaney 1937 defined the ball sie as a function of the top sie of the feed i.e. dV 0.40 KF
2015416As 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

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 charg
20181213constant ball load of 28. In the pilot scale experiments the Magotteaux ball mill at Frank Concentrator was equipped with a Sensomag sensor for measuring the toe and shoulder angles of the slurry and ball load based on the principle of conductance and induction respectively. The mill was configured to operate as a RoM ball mill.
