The 200mesh sieve is equivalent to 74 microns and usually is the smallest used in the industry. Generally coal particles minus 48mesh (295 microns) are considered dust. A few plants dedust at 28 mesh and a few at 10 and 14 mesh. Coal dust is formed by cutting, drilling, blasting, grinding, and abrasion in the mine and preparation plant.

If you plug only 500 CFM/235 l/s and 7 feet (2 m) of 4" (10 cm) flex hose into the calculator, you'll see the static pressure drop is almost 3"/ mbar, so we already need to look at a more powerful dust collector. Although this is the simplest way to size a dust collector, you don't suddenly go from 500 CFM to 0 CFM.
