Larger ball mills use trunnion bearings. How Ball Mills Work. At critical speed, the grinding mill charge clings to the mill inner surface and does not tumble. Most ball mills operate at approximately 75% critical speed, as this is determined to be the optimum speed. The true optimum speed depends upon the drum diameter.

To make it more efficient the pulp level in the drum should at least be above the level of the lower generating trunnion for unloading. On the other hand, mills whose unloading is done using the grid consist of a lifting device which helps to unload the crushed material. For this reason, in such a mill the slurry level is likely to be lower
