If the aperture of the sieve remains unchanged, the more the pulverized coal is left on, the greater the fineness, the coarser the pulverized coal. For example, pulverized coal fineness of 1012R90 means that the probability of pulverized coal passing through a sieve with an aperture of 90 microns is 8890 with a non-pass rate of 1012.

Coal is crushed to desired fineness between spheres or cylindrical rollers. After that, air from the boiler is heated to around 330°C (650°F). The raw coal is then fed into the pulverizer where it is ground into fine coal particles. What are the Advantages of Pulverized Coal? Pulverized coal produces a larger amount of heat than traditional coal.
