  • Coal Millan 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 be limited and therefore improving the fineness of milling
