Raw coal is fed through a centrally located feed pipe to the center of the grinding table. As the flat grinding table rotates, coal is gradually forced out towards the edge where it passes underneath the rollers. When the ground material leaves the edge of the table, it is met by an upward high velocity stream of hot primary air

Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs.". A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.
