Ensure clean & dry oil on rod mills, ball mills, SAG mills
Rod mills, ball mills, autogenous mills, and semiautogenous mills (SAG Mills) all have a number of lubriing and hydraulic systems, and they must work to keep mineral output high. The mill systems oil is subject to extreme levels of very fine particles, and many operators believe the plant should be shut down periodically to change the oil.

An oil pressure film develops with equal and opposite force vectors to the applied load. One surface drags the lubricant, usually an oil, into a converging gap. As the space available in this gap decreases, the fluid develops a pressure gradient, or pressure hill. As the fluid leaves the gap, the high pressure helps expel it out the other side.
