Coal Pulverizer Power Plant Pall Corporation
Pulverization of coal is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping A Comparison of Three Types of Coal Pulverizers Babcock Power

Improving Coal Pulverizer Performance and Reliability Pall
Figure 3 shows a cut-away of a Ring-Roll type coal pulverizer. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing theIntroduction. This article concerns itself with vertical grinding mills used for coal pulverization only (coal pulverizers), although vertical grinding mills can -and are- used for other purposes..

Coal Pulverizer
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.This force causes the grinding roll to grind<br /> the coal and reduce it in size. Both the<br /> grinding roll and the bowl segments will<br /> to transport the coal from the pulverizer to<br /> the boiler.
