= 3 for ball bearings = 10/3 for roller bearings, as used typically in axlebox applications The basic rating life for a specific bearing is based on the basic dynamic load rating according to ISO 281 . The equivalent bearing load has to be calculated based on the bearing loads acting on the bearing via the wheelset journal and the axlebox housing .

The ball mill is 13-ft-6-in diameter by 18-ft, and was originally intended for a rod mill application. It has a large diameter trunnion and an oversized motor. To bring the ball mill speed up to 75% of critical from 66%, the 24-tooth pinion was replaced with a 27-tooth one. Equipment selection using SPI data was deemed a success.

cleaner scavenger cells. There is a regrind mill between the rougher flotation cells and the cleaner cells. In the original design, the regrind was specified as two Vertimills, but the plant was constructed with a single ball mill in this application. The regrind ball mill is a 15.5' x 29' mill with 3,600 hp (2,687 kW) installed power.
