Ensure clean dry oil on rod mills, ball mills, SAG mills
Rod mills, ball mills, autogenous mills, and semi autogenous mills SAG Mills all have a number of lubricating 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.

Small Scale Tests to Characterise Ore Grindibility
BOND ROD MILL GRINDABILITY The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stage crushed to ½ 12.5mm and the test is run under a 100 circulating load. The test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14 mesh 1.18mm sieve is typically used.
