high temperatures in a low humidity environment, which is essentially what is done in a coal pulverizer. The raw coal is ground and exposed to a very low relative humidity. The coal enters the mill at about 80°F and then hot primary air flows over the Primary airflow through a pulverizer is generally thought of simply as transport air - the air that moves the pulverized coal from the mill to

Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

Pulverizer air flow and temperature control - Combustion

11/12/1979· Should the air flow momentarily fall below that level required to transport the coal, some of the pulverized coal will "fall out" in the pipes downstream of the pulverizer thus presenting a fire hazard when hot air later flows through the pipes. If the temperature is insufficient to dry the coal, the coal will not be ground properly and the pulverizer will "spill"; i.e., the coal will not be
