Analysis of the criticality of flaws found in trunnion of ...

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.
