Coal Dust Particle Size Survey of U.S. Mines

The term “mine size coal” was adopted in about 1925 and refers to coal dust, all of which passes a U.S. Standard No.20 sieve (850 µm) and contains 20% minus 200-mesh (75 µm). The justification for adopting it is given in Bureau of Mines Technical stone (TP) 464 (Rice and Greenwald, 1929).

Coal assay - Wikipedia

The particle size distribution of milled coal depends partly on the rank of the coal, which determines its brittleness, and on the handling, crushing and milling it has undergone. Generally coal is utilised in furnaces and coking ovens at a certain size, so the crushability of the coal must be determined and its behaviour quantified.

Fly Ash Properties - Weebly

The particle size distribution of most bituminous coal fly ashes is generally similar to that of a silt (less than a 0.075 mm or No. 200 sieve). Although sub bituminous coal fly ashes are also silt-sized, they are generally slightly coarser than bituminous coal fly ashes.
