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.

Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on ...
