d = diameter of bearing [m] n = shaft speed [rev/min] Noise of Dry Operation Bearings In dry bearings momentary variations in frictions are likely to be considerably greater than in lubricated bearings. Furthermore, there is no lubricant fluid present helping to absorb the vibrational forces which such variations produce.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
