If the VI of the lubricant deviates from this value, additional tables for oils with VI = 120 and 160 are included, or a viscosity-temperature plot can be used to interpolate the appropriate ISO viscosity grade. Figure 1. Although several common methods for gear lubricant viscosity grade selection are available, most should return similar values.

The mill was then operated at 400 rpm for 30 min using 50 milling balls of 10-mm diameter. The ball milled product (BM) was then compacted using a Carver press at 4,000-psi pressure and a dwell time of 30 s. The compacted BM was milled using a twin-blade rotary mill and then sieved between US mesh nos. 40 and 60 (250–420 μm).

Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

Oil Viscosity Grades and Standards. One of the best-kept secrets about viscosity is that a particular grade often represents a range. When oils are classified, one may see an ISO 32 or ISO 220 and believe that the oil will have this exact viscosity (32 cSt or 220 cSt). However, this is not the case.
