Coal pulverizers typically operate under challenging conditions to perform the fundamental and important task of crushing the fuel to a uniform optimum size for proper combustion in coalpowered power plants. Pulverizers, are critical to the operation of any coalfired boiler.
Since the first appliion using an MPS mill to process pulverized coal in Germany in the mid 1960s, there have been over 2,000 different MPS mill installations operating in coalfired power plants worldwide. As one of the most popular coal pulverizers in the utility industry, the MPS mill was first introduced into the US in the early 1970s.
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 .
11/11/2009 · Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler. Coal, being a heterogeneous fuel, varies in its properties; the variation depends on many factors like type of origin of coal, formation, major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.
