Ball Mill - an overview ScienceDirect Topics. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter Figure 8.11.The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.

Commercial ball sizes 10 150 mm; Number size and mass of each ball size 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 size as a function of the top size of the feed i.e. dV 0.40 KF
During normal operation the mill speed tends to vary with mill charge. According to available literature the operating speeds of AG mills are much higher than conventional tumbling mills and are in the range of 80–85 of the critical speed. SAG mills of comparable size but containing say 10 ball charge in addition to the rocks normally operate between 70 and 75 of the critical speed.

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 ...
