A Comparison of Three Types of Coal Pulverizers

2018-2-1  As the mill rotates, the balls cascade and 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 for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.

2014-10-1  Then, the pulverized coal particles move into the classifier volume (4). In the classifier volume, the gas and coal particle mixture exits the pulverizer at a velocity of approximately 30–35 m/s. This high speed forces the coal particles to the radial region of the classifier (5). However, not all of the particles follow this process.
