Oil lubrication failure on grinding mill trunnion bearings causes thermal stresses in surfaces and cracks at low stress region. • A contact temperature of 150 °C may causes a stress over the yield strength of the trunnion nodular cast iron.. The use of standard BS 7910 on fatigue crack propagation in the trunnion proved to be more accurate compared to ASME Section XI.

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

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.
