Ball mill is a kind of fly ash grinding equipment commonly used in the industry, which has great flexibility and market adaptability. However, its pulverizing fineness is limited, and it can only be used for conventional fineness (about 150-250 mesh converted into microns, which is 50-100 μm) pulverizing production.

Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh (0.075 mm) and 99 % will pass through 50 mesh (0.300 mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty.
