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.

Coal Pulverizers - an overview ScienceDirect Topics

The main boiler was built as coal-fired, which is why pellets were ground in coal pulverizers that were slightly modified for biomass and operated at low temperatures to eliminate the risk of fire. Further modernizations and the addition of a fourth mill enabled that in 2014 the boiler was commissioned for 100% wood pellets [76] .

Numerical and experimental analysis of pulverized

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.
