Critical-sized particles are those where the product of the mill feed-size distribution and the mill breakage rates result in a buildup of a size range of material in the mill load, the accumulation of which limits the ability of the mill to accept new feed. While critical-size could be of any dimension, it is most typically synonymous with ...

For example, when grinding with a 4" (101.6 mm) wide superabrasive wheel, the rest blade will generally work well at 30º. But with a wheel width of 6" (152.4 mm) or 8" (203.2 mm), that same angle may generate too much pressure toward the grinding wheel and cause chatter.

Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials). The production of fines is low and consequently a rod mill is the right machine when a steep particle size distribution curve is desired.

One can infer from examination of the formulas, that a single large peak or flaw within the microscopic surface texture will effect (raise) the RMS value more than the Ra value.
