The thermal power plant requires a pulverizer coal is ground into a fine coal particles of irregular, average particle in the 0.05-0.01mm, wherein the particles in the 20-50um (microns) or less majority. This is because the pulverized coal particles is very small, large surface, can adsorb a large amount of air, and with the nature of the general solid No – flow ability.

In the milling machine on Coal grinding, pulverized coal, into contact with oxygen and oxidation must occur pulverized auto ignition. Example: Henan Hongxing prolific MTW the top of the European version of the mill provided a special point of explosion-proof, for the release of the internal pressure of the mill.
Thermal power plants fueled with coal is often referred to as thermal coal, the classification is based on the drying of coal ash-free volatile classification. Steam coal category, mainly brown coal, long flame coal, non-caking coal, the lean coal; gas coal, as well as a small amount of anthracite. From a commercial coal, main wash mixed coal, washed coal, pulverized coal, at the end such as coal.
Thermal power plants using coal into the furnace before grinding Mill. With a very large increase in the case of vertical milling machine technology has matured, the strength of international and domestic enterprises natural duty-bound to select the preferred device for vertical milling machine as pulverized coal.
