Coal Mill - 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. In extreme cases, the performance of the boiler may
