Ball Mills Losing High Low Lube pressureGrinding
· 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.
