     · While critical-size could be of any dimension it is most typically synonymous with pebble-crusher feed with a size range of 13—75 mm. Critical-sized 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.
