What is a coal pulverizer? - Quora

A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants. Pulverizing the coal to a fine powder is an important function in the operation of a power plant.

STORM Static-Centrifugal Classifiers - Storm Technologies, Inc

These classifiers provide appropriate capability to achieve desired fuel fineness levels. A static-centrifugal classifier functions not only as a classifier, but also homogenizes the fuel distribution from pipe to pipe. This mixing function is equally important as coarse particles return to the pulverizer. STORM® designed static.
