One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.

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.
