While criticalsize could be of any dimension, it is most typically synonymous with pebblecrusher feed, with a size range of 13—75 mm. Criticalsized particles can result from a simple failure of a mill's breakage rates to exceed the breakage rate of incoming particles, and particles generated when breaking larger particles.

Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.
