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.

Babbitt metal or bearing metal is any of several alloys used for the bearing surface in a plain bearing . The original Babbitt alloy was invented in 1839 by Isaac Babbitt [1] in Taunton, Massachusetts, United States. He disclosed one of his alloy recipes but kept others as trade secrets. [2] Other formulations were developed later. [3]

A white metal bearing is essentially a composite bearing. Hard crystals are dispersed throughout a softer metal. As the bearing wears, the softer areas erode and create paths and pockets for the lubricant. The softer material also protects the bearing from damage caused by abrasive particles. Since the bearing is relatively soft, abrasive ...

This is provided by a high pressure oil pump which delivers oil between the bearing and journal. The oil, injected under pressure, lifts the mill and helps to reduce the friction between the shoe and ring, providing alignment. The minimum oil viscosity for most mills is 44 cSt at 100°C and typically requires an oil with an ISO 460 Cst viscosity.
