Wearing through trunnion liner can cause localized erosion/weakness. Lube or operational failure may have caused overheating and/or galling damage of journal surface. Other Typical, and maybe similar, reason is: Poor maintenance or operation! Contamination of lube. Washing/hosing dirt into trunnion when the feed chute leaks is another big one.

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.
