Coal Moisture: Explosion frequency remains unchanged with increasing coal moisture. Overall, there is a connection between moisture and pulverizer age. The newer units have a trend toward using higher moisture coals. Coal Ash: Explosion frequency is higher for medium ash coals than for low and high ash coals.

Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or "races." The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel.

Pulverised coal firing is done by two systems: i) Unit system or Direct System. ii) Bin or Central system. Unit System: In this system, the raw coal from the coal bunker drops on to the feeder. Hot air is passed through coal in the factor to dry the coal. The coal is then transferred to the pulverising mill where it is pulverised.

When saying "cracking into pieces", "crushing" may be used. "Crushing" refers to pulverization in the region where the particle size of the crushed material is relatively large (the maximum particle size is 1 mm or more). There is no clear boundary between grinding in a narrow sense and crushing, and the distinction remains vague.
