Dynamic classifiers were retrofitted at Central Hudson Gas & Electric's Danskammer Station to increase the capacity and improve the fineness of the existing pulverizers. The dynamic classifiers, which went on line in April 1995, replaced the existing static centrifugal cone type classifiers in CE Raymond Mills.
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.

The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fires. In most cases, pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air. Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire.
