Fineness - an overview | ScienceDirect Topics
The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.
Pulverizer Vibration Issues
The end result is that pulverizer fineness at the lower loads increases. On pulverizers with >75% passing 200 Mesh fineness at full load, minimum load fineness can be as high as 85% or more. In some instances, an excessive quantity of finely ground coal particles on the bowl acts as a powder lubricant between the roll and bowl.
